Functions and
Applications of D Registers (for UT55A/UT52A/UP55A)

6.4 UT55A/UT52A/UP55A D Registers
Writing Data (Multiple Segment Data) (D8201 to D8953)

Modbus communication
The example for the communication command is Modbus/RTU. For easy understanding,
space is added but it is not present in the actual command. The device address is “1.”
Example: Batch writing SSP_L1 and target setpoints in segments 1 to 5 (TSP_L1_S1
to TSP_L1_S5) for pattern 3
(1) Write to 52 registers continuously: pattern number “3” to D8201 (PTNO._C),
“0” to D8202 (unused), D8203 (SSP_L1), and D8204 (TSP_L1_S1) to D8252
(TSP_L1_S49).
If “PTN.ERR” in the response is other than zero, an error occurred. If zero, the write
was successful.


PC link communication
The example for the communication command is a PC link without a checksum. The
device address is “1.”
Example: Batch writing SSP_L1 and target setpoints in segments 1 to 5 (TSP_L1_S1
to TSP_L1_S5) for pattern 3
(1) Write to 52 registers continuously: pattern number “3” to D8201 (PTNO._C),
“0” to D8202 (unused), D8203 (SSP_L1), and D8204 (TSP_L1_S1) to D8252
(TSP_L1_S49).
(2) Read from D8253 (PTN.ERR).
If the result is other than zero, an error occurred. If zero, the read was successful.
