Error Flag
The interface message number specified in buffer
memory is invalid.
The “number of peer devices” or “peer device
addresses” specified in buffer memory are invalid.
The “number of receiving device addresses” or
“receiving device addresses” specified in buffer
memory are invalid.
The “peer device addresses” were not set when
making a serial polling request.
An IORD(222) or IOWR(223) instruction addressed
an address beyond the range of buffer memory.
A non-existent device address was specified in
buffer memory for the “transmitting device address”
or “receiving device address.”
The communications cable is not connected prop-
erly.
The communications peer device cannot be found. Check whether there are two or more devices with
