3 Procedures for Setting UPM100/UPM101 Functions
To set the functions of the UPM100, use the protocols described in “4. PC Link
Communication,” “5. MODBUS Communication,” or “8. UPM01 Communication” according
to the instructions in this chapter.
For details of each function, refer to the standard manuals that come with the UPM100.
For set value ranges, initial values, and data backup for registers, refer to “6. Functions and
Usage of the D Register.” D Register numbers are explained in this chapter, but refer to
Chapter 6 also for reference numbers for MODBUS communications.
The UPM100 offers registers for floating-point data. To perform settings via communication
starting from larger digits, floating-point data is displayed by IEEE754 (single precision).
Note
• The UPM100 has data (D register) the unit of which is two words. When 2-word data need to
be written or read, writing or reading operations must be performed for the 2- word data at the
same time.
• Even if data written to the D register is out of the effective range, a normal response is returned.
The part of the written data within the effective range becomes effective on the UPM100 when
the equivalent setting change status is written for that data.
