Notes:
1) If the PLC goes into stop on account of a parameter error, the number of the interface
byte is stored in the High byte of ACCU 2.
2) If several jobs are entered in the buffer for data transfer, a job with the number 65 is
processed before the others.
3) Data transfer is via function macro FB61 (Read) or FB62 (Write).
