Transmission Delay Time
Setting
Sets the transmission delay time for the B7A Interface Unit.
Set the transmission delay time to RAPID to enable transmission with high-
speed B7A Link Terminals with a transmission delay time of 3 ms. Set the
transmission delay time to STANDARD to enable transmission with standard
B7A Link Terminals with a transmission delay time of 19.2 ms.
Set the pin to match the transmission delay time of the type of B7A Link Ter-
minal connected. A transmission error will occur if the setting does not match
the transmission delay time of the B7A Link Terminal.
The transmission delay time setting is made for the entire Unit. It is not possi-
ble to make separate settings for each word if multiple words are used.
Transmission Error
Processing Setting
This setting determines whether the input bit status immediately prior to the
error is held when a transmission error occurs (HOLD) or whether all input bits
turn off (LOAD OFF).
Input Mode Setting Set the input mode (the use of bit 15) from the Input B7A Link Terminal to one
of the modes shown in the table below. Match the pin setting to the Input B7A
Link Terminal.
ERR Indicator Lighting
Setting
Sets whether the ERR indicator lights when an input transmission error
occurs.
To avoid indicator lighting unnecessarily, set pin OFF if the input side of the
B7A Interface Unit is not used.

Setting Input mode Description
ON 15-point input + 1 error
(15IN+ERR)
Bit 15 used as transmission error bit. The
bits available for input are the 15 bits from
00 to 14.
OFF 16-point input (16IN) Bit 15 also used as a normal input bit. The
bits available for input are the 16 bits from
00 to 15. (factory setting)
Setting Description
ON ERR indicator lights (factory setting)
OFF ERR indicator does not light
