Communication Check (Field Network) - Yamaha TS-S User Manual

1.1.4 Communication check (field network)
In a field network, always check that the communication state is normal before starting operation. When using
the host unit's communication status flag to monitor the communication state, allow a time delay of about
200ms after recognizing a normal state, and then start operation. If the time delay is short, the controller
output information may not be read correctly, so the operation cannot start normally.
* In the case of CC-Link, the time delay is not required if remote READY (R-RDY) is used to check whether the link state
is normal.
