Modbus-measured variables with function code "0x14"

Addressing the measured variables
The measured variables listed below can be read out via Modbus function code 0x14 "Read
File Record" in two steps.
Step 1 (File Number 1), preset to 10 s
Step 2 (File Number 2), preset to 15 min
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 PAC2200 will also output an error code if a write operation
ends in the middle of a multi-register value.
