Note
1. Bit 15 of the input address is allocated as follows, according to the DIP
switch input mode setting.
15-point input + 1 error mode setting = transmission error bit
16-point input = input bit 15
Refer to 2-2 Switch Settings.
2. Start word address (n: input, m: output)
3. See the following caution.
Caution
The minimum input time (minimum required time to read input signal from CPU)
at output bit of the B7A Interface Unit is as follows:
Transmission delay time
Minimum input time
STANDARD (19.2 ms)
16 ms
RAPID (3 ms)
2.4 ms
When a user program is created, make sure the ON/OFF signal range from the
CPU to the B7A Interface Unit’s output bit is larger than the above values. If
smaller than the above values, data might not be correct transmitted.
Transmission Errors
Power On
If the input mode is set to 15IN+ERR, the transmission error bit becomes OFF
when the CQM1H/CQM1 power is turned on.
The transmission error bit turns ON if normal transmission with the input B7A
Link Terminal is not established within 10 ms.
All input bits remain OFF from the time CQM1H/CQM1 is turned on until normal
transmission is established.
Inputs
When a transmission error occurs, the input bits are processed according to the
transmission error processing setting: HOLD or LOAD OFF.
If the input mode is set to 15IN+ERR, the transmission error bit turns ON.
The transmission error bit turns OFF when normal transmission is re-estab-
lished.
The normally received signals are then input to the input bits.
Outputs
A transmission error with an output B7A Link Terminal can only be detected at
the Link Terminal. Confirm the error with the Link Terminal ERR indicator and
error output.
