Transmission Error Precautions
Startup
The Transmission Error Flag for the B7A Interface Unit will be OFF when power is turned on to the C200HS. If
normal transmissions with the B7A Link Terminal are not possible within about 10 ms, the Transmission Error Flag
(bit 15) will turn ON (i.e., if its operation is enabled by the input mode setting).
All input bits will remain OFF until normal transmissions are achieved.
Inputs
When a transmission error occurs, input status will be either held or all inputs will be reset according to the setting
for the transmission error process, and the Transmission Error Flag (bit 15) will turn ON (i.e., if its operation is
enabled by the input mode setting). The Transmission Error Flag will go OFF and the input status will return to
normal when normal transmissions are achieved again.
Outputs
Transmission errors for Output B7A Link Terminals are not detected at the B7A Interface Unit and must be con-
firmed using the error indicators or error outputs on the Link Terminal.
