(17) Module reset request: Yn4
Signal used to reset the module for debugging.
The module can be reset individually without resetting the PC CPU.
If you cannot start the remote station earlier than starting the system in any
method, resetting the module after the start of the remote station allows the
system to start from the initial status securely.
While the module reset request is being executed (Yn4 is ON), do not execute
the FROM/TO instruction for the module.
Refer to (5) for signal timing.
(18) Data link startup request from buffer memory parameter: Yn6
Starts data link according to the parameter (address 0
memory.
Do not turn on this signal during RUN of the PLC CPU and during a data link.
If you are going to change any parameter data during RUN of the PLC CPU and
during a data link, always turn on SB0002 (data link stop) to stop the data link,
change the parameter data, and then turn on this signal to restart the data link.
Refer to (6) and (7) for signal timing.
(19) Data link startup request from E
Starts data link according to the parameter contents registered in E
Do not turn on this signal during RUN of the PLC CPU and during a data link.
If you are going to change any parameter data during RUN of the PLC CPU and
during a data link, always turn on SB0002 (data link stop) to stop the data link,
change the parameter data, and then turn on this signal to restart the data link.
Refer to (8) and (9) for signal timing.
