• When the specified target is invalid:
s = 0, SSACK = "CE" communications error
• When there is an MID length error:
s = 0, SSACK = "CE" communications error
• If the MID data contains Non-Visible ASCII characters:
s = 0, SSACK = "EE" execution error
• If the status of SSACK is other than "NO" (normal), the List of Status will comprise zero items.

• CPVAL = "PS" is a parameter setting unique to this CIDRW Controller for switching to the Setting mode.
• CPVAL1 = “CP” is a parameter unique to this CIDRW Controller that enables changing to a state to use SECS to change
parameters.
• CPVAL1 = “ST” is a parameter unique to this CIDRW Controller that validates values of parameters changed with the unique
“CP” mode.
