System Status References
Specific references in the %S memory area of the Series 90-70 PLC CPU. Some have
been assigned for FIP use.
Transport Time Slot
Each MPS exchange of a COMV on the FIP network is carried out in a time slot. The
time slot may be either asynchronous or synchronous.
A transport time slot corresponds to a time slot range which is periodic and phased
in relation to the beginning of the Bus Arbiter cycle. In a transport time slot, a set of
COMVs is transported by the network. Transport time slots are set up by the
Network Configuration Tool.
TVA
Transport Variable. A TVA is the unit of exchange between two subscribers. A COMV
contains 1 or more TVAs. A TVA is never divided into multiple COMVs. A TVA
generally carries a table of variables manipulated by the applications supported by
the devices.The tables in this appendix list the status codes that are reported in the COMREQ Status
word after the execution of a COMREQ function. These codes also may appear in Word
1 of the Detailed Channel Status words.
Status Codes are a single word containing a major code in the low byte and a minor code
in the high byte. The meaning of a Minor Status Code depends upon the associated Major Status Code.
Status Codes are grouped into the following tables:
Major Status Codes
Minor Status Codes
Minor Status Codes for Major Status Codes 05H (at Remote Server PLC) and
85H (at Client PLC)
Minor Status Codes for Major Status Code 11H (at Remote Server PLC)
Minor Status Codes for Major Status Code 14H (at Client PLC)
