Note The GP-IB Interface Unit automatically controls the ATN line status to switch

Master and Slave modes
Operation can be controlled by writing data to the Unit’s buffer
memory from the ladder program with the IOWR/IORD
instructions (CS-series and C1000H/C2000H PLCs) or WRIT/
READ instructions (CVM1 and CV-series PLCs.)

1. The Controller sets the ATN line to “L” and sends the UNL command. This
2. The Controller sends the TA (Talker address) and LA (Listener address).
3. The Controller sets the ATN line to “H” to put the bus in data mode. At this
the bus between command mode and data mode and automatically sends
commands such as UNL, TA, and LA.
A device connected to the GP-IB system can generate an interrupt to the sys-
tem Controller for a service request by setting the SRQ line to “L.”
When the Controller detects the “L” level in the SRQ line, it performs a Serial
Poll operation to identify the device that generated the interrupt. The Control-
ler performs the Serial Poll operation by requesting the transfer of each
device’s status byte in order, as shown in the following diagram.

Two or more Listener addresses can be specified. This step determines
the new Talker and Listener(s) and the relevant GP-IB devices will standby.
