Note 1. Bit 15 of the input addre ss is allocated as follows, accordi ng to the DIP
switch input mode setting.
15-point input + 1 error mode setting = transmission error bit
16-point input = input bit 15

!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/O FF signal range from
the CPU to the B7A Interface Unit’s output bit is larger th an th e 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 bi t tur ns O N if nor m al transmi ssion wit h the inpu t B7A
Link Terminal is not established within 10 ms.
All input bits remain OFF from the tim e CQM1H/CQM 1 is turn ed on until nor-
mal transmission is established.

Bit Allocation Section 1-5
Inputs When a transmission error occurs, the input bits are proces sed 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 nor mal transmission is re-est ab-
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 . Co nfirm the error wi th the L ink Terminal ERR indicator and
error output.
