smc step motor controller driver

[autohome]

hello everybody,

anybody use this smc electric linear actuators controller with labview ? they dont have any labview driver. this controller support modbus and scan for binary number to determine step number which is predefine in the controller through their own software. here is a manual http://content.smcetech.com/pdf/LEC.pdf

never use modbus communication yet, if anybody use their controller will you send me some information or an example vi please?

thanks

Hi autohome,

Here is some information about MODBUS:

and the MODBUS library for LabVIEW:

I hope this helps,

Kind regards,

Hai, 

Have you got the actuator thing moving?

Have you tried with the parallel I/O pins of LECP6 drivers? I am trying to move the actuator using parallel ports in LabVIEW. If you have a solution, please let me know.

Hello Hai,

Im also working with the SMC actuator, and try to communicate with Labview.

If you had any success with the communication, examples would be welcomed.

Thank you.

Hi,

I have an SMC actuator LEHZ20 and drive LECP6, which I have bought from eBay, I do not have the exact communication cable but a cable USB to Rj45(RS485 protocol). But The software gives me errors when communicating. Can anyone guide me to this communication?
