2.1.3. Pulse counting
➢
Register address range: 64~67(0x0040~0x0043)
➢
Supported function code: 03(Read holding register), 04(Read input register)
➢
Connection: Default is dry contact input. Short-circuit DI and COM will change input status. If user needs wet
contact input can contact to our sales personnel
contact input can contact to our sales personnel
➢
Pulse counting: Default status is 0, short-circuit DI and COM and then release will count 1. Detection method:
Read pulse counting register value by 03 function code of Modbus protocol. Maximum value of pulse counting
is 65535 and it will restart counting after exceeding 65535. Can’t reset count to 0 and restart product won’t
save count.
Read pulse counting register value by 03 function code of Modbus protocol. Maximum value of pulse counting
is 65535 and it will restart counting after exceeding 65535. Can’t reset count to 0 and restart product won’t
save count.
➢
Note
: Pulse counting won’t filter input waveform and all pulse in the range of detection will be recorded. So
input waveform should keep stable to ensure accurate count.
Example:
Detect count of the first way, send: 11 03 00 40 00 01 87 4E
Return: 11 03 02 00 00 79 87
2.2. DO output
➢
Register address range: 00~03(0x0000~0x0003)
➢
Supported function code: 01(Read coil), 05(Write single coil), 0F(Write multiple coil)
➢
Connection: DO output is Relay passive output and 4-way will use one COM together. Relay close will connect
DO with COM.
DO with COM.
Take the first way Relay control as example:
Query: 11 01 00 00 00 04 3F 59
Control to close: 11 05 00 00 FF 00 8E AA
Control to disconnect: 11 05 00 00 00 00 CF 5A
2.3. AI input
➢
Register address range: 88~89(0x0058~0x0059, voltage acquisition data), 96~97(0x0060~0x0061, current
acquisition data)
acquisition data)
➢
Supported function code: 03(Read holding register), 04(Read input register)
➢
Connection: Analog detection adopts public reference ground method to connect(signal + connects to +,
signal - connects to - and reference ground short-circuit to power ground). Voltage detection range: 0 ~ 10V;
current detection range: 0 ~ 20mA.
signal - connects to - and reference ground short-circuit to power ground). Voltage detection range: 0 ~ 10V;
current detection range: 0 ~ 20mA.
Take the first way voltage detection as example:
Query: 11 03 00 58 00 01 07 49
Return: 11 03 02 10 00 74 47
Return data: 0x1000, it’s 4096 mV
Note
: Analog detection is voltage detection and current detection, default is voltage detection and please ignore
current register value. If user needs to do 0~20mA current detection, please contact to our sales personnel.
