I purchased a YS1500/YS1700 without communications and now realize I need serial and/or Ethernet capabilities. Is this possible?
It is not possible to add the Ethernet (/A34) option to the YS1500/YS1700 controllers. However it is possible to add RS-485 (/A31) or DCS-LCS (/A32) communications. The controller has to be returned to Yokogawa for this retrofit. Contact our service department at 800-524-7378 for more information.
