Description
MPRC086444-005 provides the function of connecting MODEM with PC. The main method is to use MODEM to connect with PC and PLC respectively, and then run SSS or CPT software on PC, so as to realise the function of remote monitoring and hospital control and program debugging. The MODEM connection is divided into dial-up connection and leased line connection.
The so-called leased line connection, that is, the two MODEMs do not communicate with each other through the PSTN public switched telephone network, MPRC086444-005 use a 2-core or 4-core ordinary telephone line to connect the two MODEMs directly to achieve the purpose of communication. This method is extremely useful in the case where the upper monitoring computer and PLC are far away from each other and the site is not connected to the PSTN telephone network. In general, the ordinary telephone to the telephone exchange distance of 1KM or less, so with a dedicated line connected to the 1KM should not be a problem. Specific applicable distance users need to practice in the application of the test.
