tag specification for differnt HMI softwares

[archana_sharan 0]

Hi, The specification regarding no. of tags for HMI software of different manufacturers is really confusing. For example, if I have around 1200 DI DO and 200 AI AO connected over Remote IO nodes , what is the no. of tags we would need for an HMI software for different PLC makes: Allen Bradley RS View32 Works, Siemens WinCC. Cimplicity, Vijeo Citect given that the basis of this count is dfifferent for diferent makes. Urgent reply would be appreciated Thanx

Hello, For PeakHMI the tag count is unlimited. As are the number of devices you can connect to simultaneously, graphics, trends, etc. Others look at it as entries in the database that are monitored. Each input or output or flag subtracts from the allowed number. Good luck, Mark http://www.peakhmi.com/
