Send interface messages to control other devices in the GP-IB system. Use
the following procedure to send interface messages.
1. Write the following 3 settings into buffer memory from the ladder program.
2. Turn ON (OFF
Use the INTELLIGENT I/O READ and INTELLIGENT I/O WRITE instructions
(IORD(222) and IOWR(223)) to read and write data in the Unit’s buffer mem-
ory.
Use the following procedure to send data in Master mode.
