About PLCs This type of communication is available for PLCs that are at least version V3.3.
l l
TSX Premium via the PMMCIA TSX MDM 10 card,
TSX Micro accepting the PCMCIA described below.
The card can also be inserted in PCs that have type 3 PCMCIA card slots.
Note: For certain types of CPU, it is recommended that a PCMCIA memory card
( CALL_MODEM communication function occupying 25 Kb of program memory space) is used.
Networks and
Devices l l l
The TSX MDM 10 communication card only connects to the STN - (Switched
Telephonic Network).
It cannot be connected: to specialized links, to NNIS (Numerical Network for Integrating Services) networks, to the GSM (Global System for Mobile) network.
Third-party modem compatibility is guaranteed for modems that are designed for
COM 1 switched telephonic network. See Communication between PLCs using an
external modem, p. 81.
About Protocols The TSX MDM 10 card supports the two character formats 10 or 11 bits.
For 11 bit communication between modems, compatibility is only guaranteed with modems designed for the COM 1 telephone network.
l l
The TSX MDM 10 is incompatible with configured third-party modems: with parity, with data compression and error correction.
In ASCII, the TSX MDM 10 card allows: l in called mode: l l transmission of data coded on 7 bits l reception of data coded on 8 bits.
in calling mode: l l transmission of data coded on 7 or 8 bits, reception of data coded on 7 or 8 bits.
