Both Client (Master) and Server (Slave) capabilities are being added. The new version is expected to be available (as a firmware upgrade) in the second half of June, shipment of new units is expected in early July. The price of the IC693CMM321 will not be affected. Features/Description The Series 90-30 Ethernet Interface will support both SRTP and Modbus TCP simultaneously. The Module will respond to SRTP messages and to Modbus TCP messages. Four new COMMREQs are added for Modbus TCP. 1.Create a Modbus TCP connection using a Channel (Note: number of channels remains the same,   16. A channel is used for either SRTP or Modbus). 2.Modbus Read -Read Discretes or Words 3.Modbus Writes -Write a coil or Mutliple Words 4.Close a Modbus TCP connection   Modbus Conformance Codes 0 and 1 are supported, which is read or write single or multiple discetes or words which are contiguous. Conformance Code 2 is not supported, which is read or write multiple items which are scattered in memory. The Create a Connection COMMREQ has a unit identifier field so that a serial Modbus address can be provided to allow communication to multidropped serial Modbus RTU networks, when connected thru a VMSE (Serial to Ethernet Adapter) or a Modbus Bridge. Compatibility A firmware update will be available to add Modbus TCP to IC693CMM321-FG, this is the version with the 10BaseT RJ45 port. IC693CMM321-EF and earlier can not be upgraded.
