(RS232)
This note only applies to protocol of CS31 series 90 (non direct).
Once the VT has been connected to and disconnected from the CS31, the PLC
remains in MONITOR mode and the programming software no longer functions
properly. To get the PLC back to normal functioning, use the programming S/W to
access the “PLC commun.2" menu and select the "3 terminal emulation" option
and press the "CTRL" and "W" keys together. At the end the PLC responds by
offering the prompt sign ">".
NOTE ON DIRECT PROTOCOL: You can select the communication speed of
19200 Baud in the PLC by connecting pins #6, #7 and #8 (see fig.). This speed is
handled by CS31 only if the library module CE 19_2COM1is loaded.
NOTE: the cable supplied by ESA does not have the connection represented by
the dotted line.
