I'm wondering if there is a way to connect via RS232 a Red Lion HMI directly to a IO module via RS232 ... without using a PLC?
Is there such a thing out there .. a little network device that just creates digital IO's for relay closures, or Hex numeric commands to Linear motor drives that run stored curves by selection of Hex numbers.. Such as some of the LinMot drives.
If there is no such thing...and I must use a RS232 PLC..with an IO module (need 8 IO's) It cannot be Siemens, or Omron.. or Alan Bradley .. they want too much money for software, and updating firmware.
Gotta be simple.. and inexpensive... Thanks much for any ideas.
