Specifications
ERR Indicator
Incorporated by the B7AI1 and lit when the B7AI1's data transmission or reception is abnormal.
Connection Terminals
SIG: Connects to the SIG terminal of the B7A Link Terminal.
V–: Connects to the negative power terminal of the B7A Link Terminal.
! Caution If the terminals are not connected correctly, the internal circuitry of the B7A Link Terminal will be
damaged.
Note 1. The transmission cable must be a VCTF cable with a thickness of 0.75 mm
2. Do not wire power lines or high-tension lines along with the transmission cable in the same conduit.
Input Mode Selector
The B7AI1 incorporates an input mode selector on the back panel of the Unit, with which the following modes can
be set.

Status of the ERR indicator
The ERR indicator is lit when an error occurs. If the error is corrected, the ERR indicator is OFF at the next trans-
mission cycle.
When there is a transmission error, the B7A Link Terminal will hold the data just before the occurrence of the trans-
mission error. If there is a transmission error because the B7A Link Terminal is turned off, however, data 0 is trans-
mitted in the first transmission cycle when the B7A Link Terminal is turned on again.
Transmission errors between the C200H-B7AO1 and B7A Link Terminal are detected by the B7A Link Terminal
only. Check the ERR indicator and error bit for any error.

Weight
Note 1. The minimum input time is the minimum time required to read input signals from the CPU Unit. The ON/
OFF width of signals from the CPU Unit to the output relays of the B7A Interface Unit must be at least
equal to the minimum input time.
2. The capacity of the external power supply does not include the capacity required by the B7A Link Termi-
nal.
