Hi,
I met the “illegal instruction"error when I run the luaSciptResouce in WebSocket EMS + modbus package.
It happens on Linux ARM (not HFPU.), but does not happen on Windows10 with the same configuration.
It happens in Modbus/TCP, but does not happen in Modbus/RTU.
Did anyone see this error ? If so, could you tell me how did you solved?
I searched the google and some Linux article is saying it could happen by when it was built for different CPU/OS type, or divided by zero.
Off course I installed the correct version of distribution depend on the OS and CPU type.
<distribution used>
-Web Socket EMS:
-MicroServer-5-3-0-539-Win32.zip for windows
-MicroServer-5-3-0-539-Linux-ARM.zip for Linux ARM without hardware FPU.
- http://marketplace.thingworx.com/downloads/netcomm-wireless-6200-01/
MicroServer_80.zip (extracted from the starter kit of NetComm-6200-01.zip)
This is the original one which my edge device was certified as ThingWorx Ready.
-Modbus package
https://community.thingworx.com/community/developers/blog/2015/12/13/modbus-plc-simulator
TWEMS MODBUS Package_Linux_ARM.zip for Linux ARM
TWEMS MODBUS Package_Windows.zip for windows
<config.lua >
This error happens when I specify the Modbus/TCP as follows.
scripts.modbus_handler = {
file = "modbus_handler.lua",
name = "modbus_handler",
host = "192.168.10.50", <---This specify TCP
}
This error does not happen when I specify the Modbus/RTU as follows.
scripts.modbus_handler = {
file = "modbus_handler.lua",
name = "modbus_handler",
serial_port = "ttyUSB0", <-- This specify RTU
baud_rate = "9600",
read_timeout = "1000"
}

HI .
I could solved this error. Here I report how I solved this .
The solution is as follows.
I replaced the file (1) by (2) , then the error was not happen , and Modbus/TCP seems working fine as of now.
(1)microserver/etc/thingworx/community/clibs/socket/core.so (this came from ThingWorx )
(2)/usr/lib/lua/5.1/socket/core.so (this is part of original firmware of my M2M device ( NetComm Wirelss NTC6200) .)
I hope this helps someone who meet similar issue in future.
Thank you
Kunio
