Updated h1ecatx1 to add binary readout of ISCTEX enclosure fan status and control of ISCTEX enclosure light
Patrick, Filiberto I created a TwinCAT library named Enclosure for the control of table enclosure lights and the readout of table enclosure fans. I added the necessary code to PLC1 for the end stations to handle the fans and lights on ISCTEX and ISCTEY. Today Filiberto added a EP2328-0002 EtherCAT box after the ALS Laser Table Relay (EP2624-0002) at end X (Box 251 in the first screenshot). I updated the h1ecatx1 system manager to add this box. I linked the readout of the fans to channel 1 of this box, and the control of the lights to channel 3 of the ALS Laser Table Relay box. I have not run svn update for end Y. The channel names are: H1:SYS-ENCLOSURE_X_ISCTEX_LIGHT H1:SYS-ENCLOSURE_X_ISCTEX_FAN These are set to be in alarm at a value of True. Filiberto stated that the fans and lights are not yet connected to this box, so these channels are not currently valid. The autogenerated medm screen can be accessed from SITEMAP -> SYS -> EtherCAT overview -> H1 X1 PLC1 -> Sys -> Enclosure -> X -> Isctex
