DVP-ES2/EX2/EC5/SS2/SA2/SX2/SE&TP Operation Manual - Programming
1. Explanations on the data devices D and flags M.
M1263 Execute RS instruction with M1263 to set the data receiving as completed,
when the data receiving stops for a period of time that is longer than what
D1168 was set (The specific end word to be detected for RS instruction to
execute an interruption request). If the receiving is not started, the detecting will
not be started either.
D1168 When M1263 is ON, the value in D1168 indicates a specific end word to be
seen as an interrupt request; unit: ms. It is suggested to set this value shorter
than what the timeout value is set in D1129.
When M1263 is OFF, and the received data is low-byte of a specific word, the
interrupt (I150) is triggered.
D1123 When M1263 is OFF, the value in D1123 indicates the remaining bytes of data
to be received.
When M1263 is ON, the value in D1123 indicates the bytes of data that are
received.
M1123 After data receiving is complete, M1123 will be switched to ON, and users
should reset this flag to OFF.
M1124 When in the receiving mode, M1124 will be switched to ON, and after receiving
is complete, this flag will be OFF.
M1129
D1129
When in the receiving mode, if the time before receiving started is longer than
what is set in D1129, M1129 will be ON.
