Notes:
• If the PLC goes into the stop state because of a parameterization error, the number of the
interface byte is entered in the high-order byte of ACCU 2.
• If several jobs are entered in the buffer for data transfer, a job with the number 65 will be
processed before the others.
• Data transfer is effected by function blocks FB 61 (read) and FB 62 (write).
