Modbus RTU – Modbus/KMP TCP/IP MULTICAL® 403 MULTICAL® 603 MULTICAL® 803 Modbus register mapping The following datagrams are available for the Modbus modules: • HC-003-67: Modbus RTU inputs (In-A,In-B) and • HC-003-82: Modbus/KMP TCP/IP, inputs (In-A, In-B) The various Modbus datagrams are described in details below. Any datagrams can be used in any of the MULTICAL® XX3. Thus the same configuration can be used for all meters in your application, irrespective that the application consists of a mix of MULTICAL® 403, 603 and 803. Some registers found in MULTICAL® 803 does not exist in...

Modbus RTU – Modbus/KMP TCP/IP MULTICAL® 403 MULTICAL® 603 MULTICAL® 803 Legacy datagram, xx-yy-301 The legacy datagram not only differs in data content, but also in how data must be interpreted. The datagram is reduced and contains fixed zero-values to fill gaps for those MULTICAL® 602 registers which are not available in MULTICAL® 403, 603 and 803. The legacy datagram duplicates the same data in two different memory areas. The Modbus register range from address 1 to 169 is byte-addressed. The address is incremented by the number of bytes in the data (2 for 16 bits and 4 for 32 bits)....

Modbus RTU – Modbus/KMP TCP/IP MULTICAL® 403 MULTICAL® 603 MULTICAL® 803 MULTICAL® 803 datagram: xx-yy-302 The following tables show how the MULTICAL® 803 memory data are mapped into Modbus registers. Most values can be read at two different addresses, either as IEEE Float or as 32-bit signed integers. All registers used for units and factors are 16-bit values, all others are 32-bit Float or integer values. Modbus Register Data type Actual Power
