![]() ![]() Since 1995, Kepware has focused on the development of communication drivers to automation controllers, I/O and field devices. ![]() Kepware is the world leader in communication software for automation and offers unique experience in both OPC and embedded device communications. To enable 10 bit PPM mode the S7-200 programming cable must be set to 10 bit mode ![]() The 10 Bit PPM mode can also be used directly on the programming port of the PLC. The S7-200 PPM model allows the driver to operate in a 10 bit mode which is much more compatible with a wide range of off-the-shelf modems. If the use of the EM 241 modem module is required the S7-200 PPM model must be selected. Note: Normally the driver operates using the standard 11 bit PPI protocol. Point-to-Point Modem (PPM) S7-200 Communications Protocol (10 bit Mode).Point-to-Point (PPI) S7-200 Communications Protocol (11 bit Mode).Memory Types Supported: I, Q, M, S, V, T, C, HC, AI, AQ.Single Master Multi-drop RS485 Supported.Supports PPI (11Bit) and PPM (10Bit) protocols.Data integrity is ensured with our extensive error handling. KEPServerEX automatically optimizes your data acquisition based on client demand. Direct support for the EM241 Modem Module. Kepware's 32 bit Siemens S7-200 device driver works in conjunction with the OPC Server KEPServerEX, to provide data exchange between OPC Clients and Siemens S7-200 PLCs using PPI (11Bit) or PPM (10Bit) protocol. ![]()
