8.4 UT35A/UT32A/UT32A-D/UP35A/UP32A 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 20
(TSP_L1_S1 to TSP_L1_S20) for pattern 1
(1) Write to 23 registers continuously: pattern number “1” to D8201 (PTNO._C),
“0” to D8202 (unused), D8203 (SSP_L1), and D8204 (TSP_L1_S1) to D8223
(TSP_L1_S20).
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 20
(TSP_L1_S1 to TSP_L1_S20) for pattern 1
(1) Write to 23 registers continuously: pattern number “1” to D8201 (PTNO._C),
“0” to D8202 (unused), D8203 (SSP_L1), and D8204 (TSP_L1_S1) to D8223
(TSP_L1_S20).
(2) Read from D8253 (PTN.ERR).
If the result is other than zero, an error occurred. If zero, the read was successful.
