1. CPU Version 3 83 or newer is required to be able to use the CMM in the RX3i system Problems Resolved by Release 1 34 Title Description DNP3 Master The module does not read multiple group objects for Class 0 data When multiple group objects i e l and Al memory are performed in a single request the DNP3 module will ignore all but the first object Operations of multiple group objects should be split into multiple successive exchanges i e exchange 1 l exchange 2 Al SPL Serial I O Modbus Master DNP3 Slave CMM002 004 generates blink code 1 Sending large amounts of data without reading can cause the module to generate a watchdog expired error indicated by blink code 1 The amount of data that causes this error depends on the baud rate used For example a port configured for SPL and sending 4k bytes of data at 19 2k baud or 62k bytes of data at 115 2k baud will produce the error With DNP3 protocol the creation of change events while previous change events are being read can also produce the error DNP3 An incomplete or null response from a slave will result in erroneous values written A read operation data exchange Read Continuous Read Continuous Bit Controlled Read Single Bit Controlled that requests Ref Length 1 or greater from an outstation that does not return all or returns none of the data points requested will result in erroneous values being written to the reference addresses defi2.
