1. GENERAL INFORMATION VM-53

-1-

1-1 OVERVIEW The VM-53 Dual Communication Unit is a communication unit having two independent serial ports. This unit while inserted in a relay module slot of the VM-5H3 or VM-5W1 Instrument Rack collects static data in the rack by the MODBUS protocol and then sends it to an external host computer. In addition, as this unit can be daisy chain connected it enables data collection from two or more racks.

• Also carefully read the instruction manuals for the VM-5 monitor unit, VM-5P3 Phase Marker Unit, VM-5H3/VM-5W1 Instrument Racks, and for the respective transducer used.

• This unit is used while inserted in a relay module slot of the VM-5H3 or VM-5W1 Instrument Rack. It can be inserted in any of relay module racks. However in this case, always make the corresponding monitor unit slot blank.

• When the phase marker function is required, always use the VM-5P3 without the communication function. The VM-53 Dual Communication Unit and the VM-5P1/2 Communication/Phase Marker Unit cannot be installed in the same rack.

• For communicating the OK state (abnormal input) of the phase marker, it is necessary to connect in parallel the buffer output of the VM-5P3 to the IN and COM terminals on this unit.

• The operating temperature range is limited to 0 to 50°C with the battery (for the real time clock). The time information may be lost when the power is turned off without the battery.

• Test of cables using megger (insulation test): Before conducting an insulation test of cables using a megger, always disconnect these cables from the instrument. Also when connecting them to the instrument after the test, always short these cables once to discharge charged electrons, then connect them to the instrument. The instrument may be damaged if connected with the cables charged with electrons.

• When high baud rate communication, communication error may be happened because of over performance of host computer. In that case, lower baud rate communication is recommended.

1-2 STORAGE In case the product needs to be stored temporarily for certain reasons after its acceptance at the site, store it in a warehouse with less humidity. Note that if stored in any of the following environments, its appearance and functions may deteriorate, and also its service life may shorten. (1)There is much dust. (2)There are corrosive gases (such as SO2, H2S, etc.). (3)The product is exposed to vibration and/or high temperature. (4)The product is exposed to the direct sunshine and/or high temperature. (5)The product is exposed to water, steam and/or high humidity.

• Do not conduct any work with the power turned on.

Turn off the monitor power.

• Follow the instruction manual for the instrument rack.

Before removing the unit (rear), also carefully read the instruction manual for the

instrument rack.

• Do not directly touch the main board.

If touched, the unit may be damaged.

• VZ-65 (Configuration file for VM-53) is needed to set the communication

specifications and customize the communication data address.

• Maximum number of customizing is up to 256.

8-1 SETTING THE COMMUNICATION SPECIFICATIONS The communication specifications are set via serial communication. When conducting this setting,

use the hyper terminal of Windows.

1 Open the communication setting file (Com.txt) in the VZ-65 (Configuration file for VM-53).

2 Edit [ ] in the text and change the ID, Byte interval, baud rate, data length, parity and stop bit.

The following example is the case where each item is set as follows.

ID=3, Byte interval=20msec, Baud rate=4800, Data length=8, Parity=None, Stop bit=1

Namely,

MODBUS Slave ID=[3] Byte interval=[20] msec bps=[4800] Bit=[8] Parity=[N] Stop=[1]

3 Connect the IN1 communication connector to the PC serial communication port.

• Set the desired ID from 1 to 10 by avoiding duplication.

• The communication specifications are set as follows as default values.

For CH1: ID=1, Baud rate=9600, Data length=8, Parity=None, Stop bit=1

For CH2: ID=2, Baud rate=9600, Data length=8, Parity=None, Stop bit=1

• If communication becomes impossible for any reason, return the communication

specifications to their default values by referring to item 8-5.

• Each item thus changed becomes valid just when the power is turned on again.

8-2 CUSTOMIZING THE COMMUNICATION DATA ADDRESS It is possible to effectively capture the necessary data by customizing the communication data

address. The range in which the data can be customized is between 45001 and 45500.

1 Open the setting file (Config.txt) attached in the VZ-65 (Configuration file for VM-53).

2 Edit [ ] in the text and customize the address.

Example:

[3:0002] → [4:5001]: Copy the data in the 30002 address to the 45001 address.

[3:0004] → [4:5002]: Copy the data in the 30004 address to the 45002 address.

8-3 CUSTOMIZING THE COMMUNICATION DATA COUNT VALUE It is possible to capture the necessary data count value by using customizing function.

• When communication data is expanded, data may not be changed smoothly due to

resolution.

Example 1. Change the VM-5T installed in slot 1 with -1.00 to +1.00mm range (-1 to +1 is

communicated when default setting) to 0 to +30000 range.

1 Open the setting file (Config.txt) attached in the VZ-65 (Configuration file for VM-53).

2 Refer to address map and write current monitor range to its input address for customizing

(write 0% value of 1CH monitor range to Measure1 Input_Min, Write 100% value of 1CH

monitor range to Measure1 Input_Max).

Example:

[4:3033] ← f -1.00 : 0% range of slot 1 (VM-5T) is -1.00.

[4:3035] ← f +1.00 : 100% range of slot 1 (VM-5T) is +1.00.

3 In addition, refer to address map and write the necessary data count value to its output address

for customizing (write 0% value of the necessary data to Measure1 Output_Min, write 100%

value of the necessary data to Measure1 Output_Max).

Example:

[4:3037] ← f 0 : The necessary 0% range of slot (VM-5T) is 0.

[4:3039] ← f 30000 : The necessary 100% range of slot (VM-5T) is +30000.


5 Start up the hyper terminal. (refer to P30)

6 Enter “CR” 5 times after connection. Thus the prompt is displayed to activate the terminal function.
