January 2012 9.11 Data Transfer by PLC 1801
Module 9105 Transmit binary data through data interface
You must first assign the interface to the PLC and initialize it with Module
9100.
Module 9105 transmits a block of binary values from the word memory of the
PLC to one of the two interfaces. The transfer is in the form of ASCII-coded
hexadecimal values. Every byte in the source block makes two ASCII
characters at the interface.
Can only be called in a submit job or spawn job!
Call:
PS B/W/D/K <>Interface>
0: RS232
1: RS422
PS K/B/W/D <>Number of the first byte in the binary block>
PS K/B/W/D <>Length of the binary block (0 to 63)>
