A.1.4 Modbus measured variables with function codes 0x14, 0x03 and 0x04
Addressing the measured variables
The measured variables listed below can be read out via Modbus function code 0x14 "Read
File Record".
Stage 1 (File Number 1), default setting 10 s,
Stage 2 (File Number 2), default setting 15 min.
The values are also mirrored in the address space of function codes "0x03" and "0x04", see
column "Address FC0x03 FC0x04".
Note
Error in the case of inconsistent access to measured values
Please ensure the start offset of the register is correct when making read accesses .
Please ensure the start offset and the number of registers are correct when making write
accesses .
Example: If a value consists of two registers, a read command applied in the second register
will generate an error code. The PAC2200CLP will also output an error code if a write
operation ends in the middle of a multi-register value.
