9. COMMUNICATION DATA DESCRIPTION
IMS01T28-E4
9-94
Control RUN/STOP holding setting
RKC communication
identifier X1
Modbus
register address 035AH (858)
It is set whether or not the operation mode before the power supply is turned off is held when the power
supply is turned on or power failure recovers.
Attribute:
R/W
Digits:
1 digit
Number of data:
1 (Data of each module)
Data range:
0: Not holding (STOP start)
1: Holding (RUN/STOP hold)
Factory set value:
1
Related parameters:
RUN/STOP transfer (P. 9-16), Hot/Cold start (P. 9-63),
Start determination point (P. 9-64)
When “0: Not holding (STOP mode)” is selected, the action at restoration of power will be as
follows.
Operation mode when power failure
recovers
Output value when power failure
recovers
STOP mode
Started in the control stop (STOP) state
regardless of the RUN mode before power
failure. *
Manipulated output value at STOP mode
* If changed to RUN from STOP by RUN/STOP selection after start, set to the operation mode before power failure occurs.
Interval time
RKC communication
identifier ZX
Modbus
register address 035BH (859)
RS-485 sets the transmission transfer time to accurately assure the sending/receiving selection timing.
Attribute:
R/W
Digits:
7 digits
Number of data:
1 (Data of each module)
Data range:
0 to 250 ms
Factory set value:
10
The sending and receiving of RS-485 communication is conducted through two wires;
consequently, the transmission and reception of data requires precise timing. Then, set the
desired transmission transfer time to secure the time until the transmission line is changed to data
receiving after the host computer ends its sending.
The controller’s interval time must match the specifications of the host computer.
