S9F7 responses
An S9F7 response is given when a message in an illegal format is received from the host device.
"Illegal format" here means that there is a problem with the message composition, such as illegal attributes, or insuffi-
cient or too many items. If other problems relating to the item contents arise, the response is SSACK = "CE" (communi-
cations error).
Communications with the Host Device
Communicate with the host device only after confirming that the CIDRW Controller has started. Also, unstable signals
may occur at the host interface when the CIDRW Controller is started. When initializing operation, clear the reception
buffer at the host device or take other suitable methods to clear unwanted signals.
