4 4-28 T CP/IP Ether net Communications User ’s Manual – Januar y 1996 GFK -1004B Each channel has a dedicated pair of bits as follows: (Status Bits 17, 19, 21 ... 47) Data T ransfer Bit: This bit is normally set to 0. It is pulsed to 1 and back to 0 on successive PLC scans each time a transfer completes successfully .
4 4-29 GFK -1004B Chapter 4 Programming Communications Requests Communications Status W ords The COMMREQ Status word (CRS word) and the first word of the two Detailed Chan- nel Status words (DCS words) report status and errors in the same for mat, as shown be- low .
