Section 3 - Function

Control Modes There are three different control modes are available in priority order: Balance, Man and E1.

Active mode is indicated on the faceplate and object display. These modes can also be blocked individually from operator access. When in one particular mode, control from other location is blocked. Balance Mode

In Balance mode, the control output follows the input parameter BalRef. Balance mode can be activated by setting the input parameter Local or BalIn of the function

block. When activated by input parameter Local, an indication BaLo is presented in graphic elements and faceplate. When activated by input parameter BalIn, an indication Bal is presented instead. Manual Mode

Manual mode is the default init mode of the Man01. Manual mode can be activated as long as Local and BalIn is not active.

In this mode, operator directly sets the control output from the faceplate’s dialog entry window. Manual mode can be activated from the Man button on the faceplate or with a rising edge pulse to the input SeqMan of the function block. An indication M or Man is presented on the graphic elements and faceplate. To enable Man button on the faceplate, the input parameter ManEnbl must set to True.

Manual mode can also be activated by the setting the input parameter Clamp of the function block. The output will follow the input parameter ClampRef. An indication MCp is presented on the graphic elements and faceplate. During this condition, the output value set by operator is ignored. E1 Mode

In this mode, the ratio is controlled by the input parameter ExtRef. As long as Local, BalIn and Clamp is not active, E1 mode can be activated from the E1

button on the faceplate or with a rising edge pulse to the input SeqE1 of the function block. An indication of E1 is presented on the graphic elements and faceplate. To enable E1 button on the faceplate, the input parameter E1Enbl must set to True.

3BTG811792-3026 / A

The table below describes the control mode activation and priority of Man01. Signal Balance Manual E1 Input Local (1) BaLo - - Input BalIn (1) Bal - - Input Clamp (1) - MCp - Operator Man - M - Input SeqMan (2) - M - Operator E1 - - E1 Input SeqE1 (2) - - E1

1. On leaving Balance or Manual Clamped, Manual mode is always obtained, unless other signal commands another mode. 2. The arrow indicates that only a rising edge signal will trigger the mode change.

Range Range parameter can be set from interaction window. It includes Min, Max, Decimal / Fraction

and Unit.

Signal Status Man01 monitor the MV status which connected to IO module using input parameter AIErr.

Error occurs if the IO module function is deemed nonfunctional. Typical caused of errors are missing or faulty hardware and out of range values.

Errors generated from IO module are passed to Man01. The output parameter OutPar.AIErr is set to True when there is error. Faceplate element Status gives detail information about the error code.

Overflow or underflow will occur if the A/D converter is given value out of its range. In interaction window, it’s possible to select no error when overflow to prevent alarm from being generated.

Output Limitation The control output value is normally limited to the Max and Min of the output signal, but it’s

possible to define upper limit H and lower limit L within the signal range.

Internal output limit can be entered from interaction window or extended faceplate. It can also be set externally in logic via input parameter EOHL and EOLL. The activation of input parameter EOLim determines whether external limit or internal limit is applied to the output limitation.

The upper limit can be set equal to the lower limit, but lower limit cannot be set greater than the upper limit.

For upper limit, the value of Out_EQ_HL will be set when Out H. It will be reset when the Out is lower than the output limit. For lower limit, the value of Out_EQ_LL will be set when Out L. It will be reset when the Out is greater than the output limit.

3BTG811792-3026 / A

Ramp Function Ramp function is introduced into the signal path to determine the maximum permitted rate of

change of certain signal. The maximum permitted rate of changed is determine by the input parameter Speed(x) and is specified in unit per second.

Speed2 determine the maximum change rate for ExtRef1 in E1 mode. Speed determines the maximum output Out change rate in Manual or Clamp mode.

Tracking Man01 has tracking function built in for the manual output signal. It can be configured to track

the MV or ExtRef. Tracking selection is configured using input parameter Track_A and Track_B. Track_A Track_B Description

0 False No tracking (default value) 0 True No tracking

1 False The output reference is tracking MV when in E1 mode. The output is ramped to ManOut Reference on return to Manual mode

1 True The output reference and ManOut Refrence is tracking MV when in E1 mode. The Output will stays at current value on return to Manual mode

1 False The output reference is tracking ExtRef when in E1 mode. The output is ramped to ManOut Reference on return to Manual mode

1 True The output reference and ManOut Refrence is tracking ExtRef when in E1 mode. The Output will stays at current value on return to Manual mode

Alarm Limits Man01 monitor the measured value MV and compared it with two upper (H1 and H2) and two

lower (L1 and L2) alarm limits. When determining the MV alarm limits, it is recommended to follow the rule: H2 > H1 > L1 > L2. Alarm limit can be entered from interaction window or extended faceplate.

It’s possible to select whether the hysteresis is in unit or in percentage. If percentage is selected, then actual hysteresis used internally is calculated by multiplying the percentage against the signal range.

For upper alarm limit, the value of MV_GT_H1 and MV_GT_H2 will be set when MV > H1 and MV > H2 respectively. It will be reset when the MV is lower than the alarm limit minus the respective hysteresis. For lower alarm limit, the value of MV_LT_L1 and MV_LT_L2 will be set when MV < L1 and MV < L2 respectively. It will be reset when the MV is greater than the alarm limit plus the respective hysteresis.

The value of MV_GT_H2, MV_GT_H1, MV_LT_L1 and MV_LT_L2 will always be monitored even if the alarm and event is not activated (AEConfig set to 0).

All alarm limits can be blocked altogether or individually. Alarm blocking can be done from faceplate or from function block using AlcBlk or MVAlarms.

3BTG811792-3026 / A

Interlocks The Man01 control can be interlocked by signals from the process or control logic. Interlocks

are active when the value is False. There are 4 process interlocks available: IB1 - IB4. All can be configured to accept blocking by the operator.

When interlock is active, the control output will be set to a value defined in the IB1Ref - IB4Ref. If the active interlock is at the IB1, the output will be set based on value in IB1Ref. The same condition applies to IB2, IB3 and IB4. Interlock supervision is performed in the priority order IB1, IB2, IB3 and IB4.

These interlocks do not change the current control mode, but can be overridden by Manual Forced, when selected by the operator. If the control mode is Manual when the interlock is released, the behavior of the output will depend on the value of TrackIB parameter.

The output will stay at the interlock-value if TrackIB is set to True (default value). If interlock-value is outside of the output limitation, the output will go to the limit value. If TrackIB is set to False, the output will return to the last manual entered output value when interlock is activated. This value is shown in Control 2 faceplate tab.

Interaction Window Interaction Window is used to configure the object’s parameter in the Control Builder. It is only

accessible when Control Builder is in Online mode by right clicking the function block.

The main Interaction Window shows the name and description of the function block. The buttons are link to open the sub-window.

1. General Par Name and Description can be entered from interaction window or from the function block

parameters directly. After performing Name Uploader, these values will be used as Object Name and Description and shown in faceplate.

Class defines the process section or area in which alarms are grouped. By utilizing Class, the alarms can be filtered. Valid values are 1 - 9999. Severity defines the alarm priority for general alarms. Valid values are 1 - 1000 where 1000 is the highest priority.

3BTG811792-3026 / A

2. Event Block & Init Mode Event Block is used to block the event message generated due to changes in value from logic

connection. To enable event for selected message, press the button to set the value to 0. The text message for each event is stored in the AE Translator aspect. List of events for all operator activity is managed in 800xA system with Audit Trail functionality.

Init Mode defines the initial mode of the object when cold download is performed. By default, the init mode for Man01 is Manual mode.

3. Interlock Setting When Block Event is disabled (set to 0), changes in value of the interlock will generate an

event message. The text message for each event is stored in the AE Translator aspect.

Enabling the Opr Block (set to 1) will give operator the possibility to override the interlock(s) from faceplate.

4. Unit & Range Unit & Range covers minimum and maximum range, unit and decimal number.

Limit Control defines the percentage value of changes for Output (in Man mode) when faceplate button Dec or Inc is pressed. It also defines the High and Low Limit of Output operator can enter from faceplate when in Manual mode.

Enabling Show Actuator Position will show the actuator value in the faceplate.

3BTG811792-3026 / A

5. Alarm Setting Four MV alarm limits can be configured, two high limits and two low limits. Each alarm limit

has its own configuration and can be defined individually. AE Config can be set in 3 different ways: 0 = No Alarm or Event will be generated 1 = Alarm and Event will be generated 2 = Only Event will be generated

If AE Config is set to 1, alarm will be generated if the limit stays active longer than alarm delay time. Otherwise, alarm will not be generated.

When MV Alarm Hysteresis in Percentage (%) is activated (set to 1), the hysteresis will be in percentage and calculated against the range.

Text Configuration Text Configuration aspect is used to define the text properties of the object, such as modes,

interlocks and info texts. It is accessible in the Control Structure. The length of the each text should not exceed more than 50 characters, except for modes name which is limited to 10 characters only.
