H91
Missing expansion slave unit error
(Note 1)
It occurs when an abnormal telegram is received. When there is a format error in the header of an
individual protocol, the communication discards the received data and a response reception timeout
occurs.
(Note 2)
It occurs when the communication control I/O relays corresponding to the communication port (master
communication clear to send flag, master communication send active flag, master communication
send done result relay)are not allocated as I/O words of the CPU unit in the I/O map. It occurs only
when the number of user connections of ET-LAN is expanded and this instruction is executed
specifying the expanded connections.

Precautions for programming
● Describe the UNITSEL instruction immediately before the RECV instruction and specify the
slot number of the FP7 multi-wire link unit in [S1] and "0" in [S2].
● For FP7 multi-wire link unit, the RECV instruction executes the transmission and reception
by MEWTOCOL-DAT (fixed).
