Logic Block Instructions

Overview Logic Block instructions are the commands and instructions used to create the ladder logic

routines supported by the HMC7000 Series. Over 100 instructions are available making the

HMC as flexible as using a PLC. The ladder logic can read/write to any internal memory of the

HMC including memory addresses allocated for use by the I/O expansion modules. Note that

although the ladder logic programs cannot directly access any memory of a PLC that is attached

to the HMC’s serial ports, you can still exchange data between the PLC and your ladder logic

programs by using the ‘Copy HMI Block to HMI/PLC Block’ and ‘Copy HMI/PLC Block to HMI

Block’ task commands (for more information on using these and other tasks, please read

Chapter 8 – Task Management).

The previous chapter discusses how to create ladder logic routines as well as the various types

of Logic Blocks supported. This chapter focuses on the ladder logic instructions available and

how they work.

Ladder Instruction Table The table below is a brief listing of all ladder logic instructions available. The instructions are

split into groups according to similarity of purpose. Later in this chapter, each instruction will be

dealt with in more detail.

Instruction 88- Watchdog timer reset

Expression:


Function:

When the input is ON, this instruction extends the watchdog timer reset time. A watchdog

timer is a timer that runs in the background. If the timer reaches its preset timeout value, then

it forces a reinitialization of the HMC7000. This is a safety feature that forces the unit back to a

known state in case something unexpected happens. Therefore, under normal conditions, the

watchdog timer would never time out before it was reset by the HMC7000. However, you may

have an unusually long ladder logic program or a subroutine that causes the scan time to exceed

200 msec. This instruction can be used to extend the watchdog timeout by multiple of 1msec.

(i.e. if n = 1 => 201ms; if n = 100 => 300ms).

Instruction 94- PID1

Expression:


Function:

This function performs a PID (Proportional, Integral, and Derivative) calculation based upon

fourteen input values. Basically, a PID controller is used to monitor some measureable process

variable in a control system and determine how it varies (the “error” value) from a desired

setpoint. The PID controller then adjusts an input to the control system to minimize the error

value. The name is derived from the three basic mathematical functions that are performed in

order to derive the output:

Generally, the Proportional value tracks the present error, the Integral value tracks the

accumulation of past errors, and the Derivative value predicts future error based upon the

current rate of change. MAPware-7000 provides two PID controller instructions that are based

upon two different formulas.

PID1 is based upon the following formula:

--------P--------|------------------I-----------------|---------------------D-------------------|

M= Kp * (e-e-1) + INT ( | Kil | * e + Ir / |Kih| ) + INT [ (|Kdh| / |Kdl|) * (2P-1-P-P-2)]

where:

M= manipulation or control value

Kp = the proportional gain constant

e = deviation or error value

e-1 = deviation of prior computation

Kih = the integral gain constant (high limit value)

Kil = the integral gain constant (low limit value)

Kdh = the derivative gain constant (high limit value)

Kdl = the derivative gain constant (low limit value)


1010-1041 rev. 00

Ir = the data remainder of the Integral computation

S = setpoint value

P = present value

P-1 = the present value of the prior computation

P-2 = present value of the second to the last computation

G = gap constant at which the deviation error is considered to be zero (i.e. no

adjustment required). If the calculated error falls within +G, then the deviation is set to

0 (see graph below).

L = limit constant used to limit the deviation error to minimum/maximum value. In

other words, if the calculated deviation error e is greater or less than L, then e is set to L.

Notes:

The INT symbol refers to the integer quotient after division. For example, the integer quotient of INT (18/5) is 3.

The absolute value symbol (ex. |Kil|) is used to indicate that the absolute value is used for the computation.

If KIH=0 the integral calculation is not executed.

If KDL=0 the derivative calculation is not executed.

All ranges are considered to be -32767 to +32768. If the output value M is calculated to be outside of this range, then the lower/upper range limit is used.

Instruction 95- PID4

Expression:


Function:

This function performs PID (Proportional, Integral, and Derivative) control which is a

fundamental method of feed-back control.

The basic idea behind the PID controller is to read a sensor, then compute the desired actuator

output by calculating proportional, integral, and derivative responses, then sum those three

components to derive an output value.

PID4 is based upon the following formula:

--P--|------------------I---------------------|---------D----------|

M= M-1 + KP * (e – e-1 + (e/TI) * (TS+1)) + KD(e – 2e-1 + e-2)

where:

M= manipulation value (range: 0 to 4095)

M-1= previous calculated manipulation value (range: 0 to 4095)

Kp = the proportional gain constant (range: -32768 to +32767)

e = deviation or error value;

if Action Type = reverse action then e=S-P;

if Action Type = forward action then e=P-S

A = Action Type (range: 0 for forward, 1 for reverse); this determines if the manipulation

value increases/decreases as the present value increases. For example, if you have an

electric heater, you would want the manipulation value to increase as temperature goes

down (i.e. reverse action so e=S-P). On the other hand, if you have a control valve used

to put cold air into a system, you would want the manipulation value to decrease as

temperature goes down (i.e. forward action so e=P-S).

e-1 = deviation of prior computation (range: -32768 to +32767)

e-2 = deviation of second to last computation (range: -32768 to +32767)

TI = integral time value (range: 0 to +32767)


1010-1041 rev. 00

TS = the scan interval (range: 0 to +32767)

KD = the derivative gain constant (range: -32768 to +32767)

S = setpoint value (range: -32768 to +32767)

P = present value (range: -32768 to +32767)

GP = the gap or dead-band value. A dead-band limit causes the PID instruction to only

execute when the error value is less than the dead-band value. The dead band must be

given as a percentage of the setpoint value (i.e. range is 0 to 100). For example, if

GP=10, and S=200, then 10% of 200 is 20, so the dead-band gap is the range of 180-220.

Notes:

When the PID instruction is not executed, the manipulation value (M) is set automatically to 0 or 4095, depending upon:

if S > P then M=4095

if P > S then M=0

Example:

When B010 is ON, the FG instruction finds the function value f(x) for x = XW004, and stores the

result in D0100.

The function f(x) is defined by 2 * 4 = 8 parameters stored in D0600 to D0607. In this example,

these parameters are set at the first scan.

Parameter table

4 registers for x parameters and subsequent 4 registers for corresponding f(x)

parameters plotted on a graph:

The Function Generator instruction interpolates f(x) value for x based upon the

parameters of (xn, yn). For example, if XW04 is 1500 (x = 1500), the result 1405 (f(x) =

1405) is stored in D0100.


1010-1041 rev. 00

Notes:

The order of the x parameters should be x1 < x2 < ... < xi < ... < xn. In other words, the data table should be constructed so the X values go from lowest value for X1 to the highest value for Xn.

If input value in Register A is smaller than x1, then y1 is given as f(x). In this example, if XW04 is less than D0600 (-2000), then value in D0100 would be D0604 data (-1800).

Similarly, if input value in Register A is greater than xn, then yn is given as f(x). In this example, if XW04 is greater than D0603 (2000), then value in D0100 would be D0607 data (1800).

The valid data range is -32768 to 32767.

Notes:

Future date and time cannot be used as subtrahend A.

In the calculation results, 1 year is 365 days and 1 month is 30 days.

Answer: 3 months (90 days) + 7 days + 1 hour + 30 minutes= 97 days, 1 hour, 30 minutes
