(10) Trouble no information time setting area (Buffer memory address:
2084 (824
H
))
Set the time at seconds unit, which does not inform the communication trouble
after the exchange start. Default value is 20 seconds so the communication
trouble is not informed for 20 seconds after the exchange start. By this setting, in
case the master power supply ON is faster than the slave power supply ON etc.,
it makes possible to prohibit an error that occurs temporary when system starts
up.

H
) to 2116
