Data base server
The GridVis software works with an additional program as a service on the server. The user does not have to be logged on. For measurement value analysis, the client computers access the server directly through the network. Any number of client systems can access the measurement data within the database. The presentation of online measurement values is dependent upon the number of ports per unit i.e. the client computers directly access the UMGs for online values and for historical data from the database. The following graphic illustrates this:
The UMG 507E, for example, currently has 6 communication ports. Two of these ports are designed as a gateway (port 8000) for downstream RS485 units. The ports can be allocated as follows: Port 1 = database server for downloading the UMG memory by automatic download Port 2 = client computer 1 accesses the online values from UMG 507E and UMG 96S Port 3 = client computer 2 accesses the online values from UMG 507E and UMG 96S Port 4 = client computer 3 accesses the online values from UMG 507E Port 5 = BMS (Building management software) accesses the online values from UMG 507E Port 6 = OPC server accesses the online values from UMG 507EApplication
