I am looking for a method to monitor if I’m collecting data into a serial port. I have code that was functioning on a different HMI, but am trying to get it to work on CMT3092X and am not having any luck yet. Do you have any serial communications strategies/debug tools that you can recommend?
I am using Free Protocol to talk to “LT2000 HA” which is a laser with COMM 3RS232 interface (9600 baud. I see that I’m getting a string back now by modifying the code but hoping there is an easy way to ‘sniff’ serial port for future reference.
If i want to use simulator with RS232 device, can I plug this into my laptop and use ONLINE SIMULATION? Do i need to redefine the port number in the project so it matches the COM port # in my laptop?
Currently, the easiest way to determine if you are receiving data is to use the “INPORT()” command. Also, it is possible to perform an online simulation with an RS-232 device as long as you configure the serial port you intend to use within the driver for your USB-RS-232 device in the device manager:
Open the “Device Manager” in windows and locate the USB-RS-232 driver:
Ensure that the COM port used by this driver matches the COM port used within EasyBuilder Pro:
