</parsererror> Overview
SNTest.exe is a demo program to show how to use EIService SDK API to do a Modbus data read action from Modbus register or data write action to the register.
Modbus Simulator
Start ModSim32 and configure the register for the demonstration:
- Set Holding Register data address: 0001 (From first Holding Register address)
- Set Length: 8
- Set data from address 40001 ~ 40008, for example 101, 102 , 103 …
WISE Agent and Modbus Plugin
Configure Modbus Plugin settings (Modbus_Handler.ini) as showed below for the demonstrations:
[Platform]
Name=WISE-4012E
Protocol=Modbus_TCP
ClientIP=127.0.0.1
ClientPort=502
UnitID=1
Interval=1
#Interval: The time delay between two modbus access round in second.
Delay=0
#Delay: The time delay between two modbus access in millisecond.
#Delay=0 means no delay.
Log=0
[Holding Registers]
numberOfR=3
R0=0,Data0,-1000000,1000000,1,V,0,""
R1=1,Data1,-1000000,1000000,1,V,0,""
R2=2,Data2,-1000000,1000000,1,V,0,""
;tag = offset, name, min, max, precision, unit, data type, lua script
