● Error Flag Specifications
*1: When the slave station 1 communication fails once
⇒ RXm6 will be turned on. If the radio communication succeeds in the next cycle, it will be set
back to off.
*2: When the slave station 1 radio wave environment is not good and transmission/reception does not
succeed even after the radio timeout time or longer time elapses
⇒ RXm7 to F will be turned on. If the radio communication succeeds in the next cycle, they will
be set back to off.
(If a communication abnormality occurs in the slave station, correct transmission of
information of the extension unit will be unavailable; therefore, the extension
communication error flag will be turned on simultaneously.)
*3: When a communication error occurs in the extension unit station no. 1 connected to the slave
station 1
⇒ RXm8 will be turned on.
