presservice Posted November 5, 2018 Report Share Posted November 5, 2018 Dear all! Is there any possibility to use encoders with SSI - Serial Synchronous Interface together with UniStream system? The connection via SSI is for absolut encoders very stable, fast and simple to use. And a unexpensive option for the rotary and linear position encoders. I´m just missing the respective input modul in Your portfolio. I intend to use the UniStream to control retrofited machinery - mecanical presses. They are running up to 40 cycles per minute, by resolution of min. 360 degree I need to read in a fresh value at least every 4 ms. Modbus or TCP/IP is not capable of this and is very rare to find encoders with this interface. About CAN bus I´m not sure and I can not spent months for basic science and experiments. Bitparallel is obsolete and expensive, and if the customer would discover it... they would laugh. Any ideas / sugestions? Thanks and regards Tomas Quote Link to comment Share on other sites More sharing options...
MVP 2021 kratmel Posted November 5, 2018 MVP 2021 Report Share Posted November 5, 2018 I'm servicing some mecanical preses with incremental encoder and PLC based CAM controller. Only one problem with this type of machine - need to be hand operated to place in to "0" position when power off in no "0" position. Some machine with VFD make this homing with no problem in auto mode. Maybe this solution is the cheapest with Unitronics OPLC. By the way CANopen absolute encoder is the fastest solution with simple programming in Unitronics software. Quote Link to comment Share on other sites More sharing options...
dorelian Posted November 6, 2018 Report Share Posted November 6, 2018 You could use such converter SSI to analog https://www.kuebler.com/k2014/j/en/produkte/details/uebertragungstechnik/lwl/SK1S1A2RS or may be this on could help you https://www.kuebler.com/k2014/j/en/produkte/details/uebertragungstechnik/lwl/SK1S1P Quote Link to comment Share on other sites More sharing options...
