    Anyone still following this.... Logo! SoftComfort V8.2 SP1 is available.

    Also other PLC manufacturers are getting on the Ethernet programmable PLC/relay bandwagon.

    Similar range & configurations to Siemens.
    - Dev software with functional block diagrams looks similar.
    - Uses 32bit values & BCD values instead of Siemens fixed 16bit.
    - Access to real time clock, a real boon for fish tank timer.
    - Various conversion functions, BCD to 32bit as well as more mathematical functions.
    - Look up tables and recipes, so could easily implement normal, holiday & long holiday functions by using lookup table/recipe to control timing.
    - Can be programmed in EDP, event driven programming (text file input).

    Starter kit is only £140 including development & programming software, which is only slightly more than just the module cost.
