I need to have three computer screens at different locations set up reading the same data. 1st the screens need to handshake who is the master including a lock out mechanism that prevents two other screens from gaining control of the first screen. I think I can manage this handshaking.
The real question is Do I need three run-time copies to do this or can 1 copy run on 3 different screens. The sales man wants to sell me three (15- screen) run time copies.
The next question is" Is it possible to multitask the screens. In RSVIEW32 you can purchase 150 tag based system and take 100 tags and multiplex them (Compact logix) by 32 that means that 100 tags become 3200 individual tags.
I am thinking if you have 4 extruders and we have heating setup screens that are identical then just by changing one bit on that screen (IE: extruder#1 to Extruder #2) then the screen has not changed but the data is now relevant to Extruder #2. I think this is possible provided the screen can be identified by the PLC. I am worried about running out of screens when accessing 3 - 4 extruders.
Anyone with some experience in this ??
Also I have version 7.0 but I have not paid Rockwell their $ 1000.00 yearly maintenance fee so can I develop on 7.00 and install this on v8.00 run -time ??? If not does this mean my customer is also forced to upgrade ??
