8.4 UT35A/UT32A/UT32A-D/UP35A/UP32A D Registers
Reading Pattern Data (D8001 to D8100)

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.”

Reading start segment data
Example: Reading start target setpoint (SSP_L1) for pattern 2
(1) Write pattern number “2” to D8001 (PTNO._C), and segment number “0” to D8002
(SEGNO._C).
(2) Read from D8003 (SSP_L1).
(3) Read from D8042 (PTN.ERR).
If reading PTN.ERR results in other than zero, an error occurred. If zero, the read
was successful.
(1) 01 10 1F40 0002 04 0002 0000 [CRC]
(2) 01 03 1F42 0001 [CRC]
(3) 01 03 1F69 0001 [CRC]
Example: Batch reading start segment data for pattern 2
(1) Write pattern number “2” to D8001 (PTNO._C), and segment number “0” to D8002
(SEGNO._C).
(2) Read from 40 registers continuously: D8003 (SSP_L1) to D8041 (P.NAME) and
D8042 (PTN.ERR).
If reading PTN.ERR results in other than zero, an error occurred. If zero, the read
was successful.
(1) 01 10 1F40 0002 04 0002 0000 [CRC]
(2) 01 03 1F42 0028 [CRC]

PC link communication
The example for the communication command is a PC link without a checksum. The
device address is “1.”

Reading start segment data
Example: Reading start target setpoint (SSP_L1) for pattern 2
(1) Write pattern number “2” to D8001 (PTNO._C), and segment number “0” to D8002
(SEGNO._C).
(2) Read from D8003 (SSP_L1).
(3) Read from D8042 (PTN.ERR).
If reading PTN.ERR results in other than zero, an error occurred. If zero, the read
was successful.

(2) 01010WRDD8003,01
(3) 01010WRDD8042,01
