    Connection by US Robotics sportster 56K external modem. Thru Null Modem Adapter (25 male to 25 male), DB25 to DB9 converter, SNP Cable, PLC. The software is Versapro professional Edition 2.03 with Special 5 and Cimplicity Machine Edition 3.0 SP6, 4.0, 4.0 SP1 and 4.0 SP2. Pinouts for Null Modem Adapter 1 - 1 2 - 3 3 - 2 4 - 5 5 - 4 20 - 6 & 8 7 - 7 6 & 8 - 20 Refer to the following for modem in versapro and CME: http://elitenet.geindustrial.com/techadvisor/servlet/ksb/,/?E=0000000000002254506,K=3070,ST=93,Case=obj(598) Some time you need to use AT command to configure the modem. check the manual for modem for AT command. For CME, after the configuration in operating system, you need to restart your computer to make it available in "Physical Port" for target. If you connect the modem to PLC without null modem adapter, you will see two modems handshaking for a while and then disconnect. But with Hyperterminal, the connection can be made. The issue is the wiring between PLC and the modem. Refer to the log file errors for the modem in operating system. When modem sends an attached message to PLC, never gets a feedback and this is the reason why modem cannot get the connection for a while. Connecting thru serial port on CPU(352), fails but works thru the powersupply.

    If the PLC was programmed with the same version, and logic is not equal using the same version, you can try the following to gain equality. Open the project in versapro (same project which was stored into PLC) then perform a ' Check All ' (Folder then choose Check All). After doing this, logic should then be equal, if not, then you can do a download back into the controller
