Scada Notes

Q1. How do we have local variables on the PC ( not PLC ) that are accessible by all the different Iconics Applications ? A1. Configure Items in Unified Data Manager so that the item is accessible by the GraphWorX  as well as ScriptWorX Example : UDMConfig --> Registers (New Bool1, Writeable) ____________________________________________________________________________ Q2. How do we log PLC Item data to a .csv file Trigger Tag is created  in UDMConfig --> Registers (New Bool1, Writeable) Configure Tag as reg:Bool1 Trigger is configured in the UDMConfig --> Event trigger --> Data Trigger (New) -> Data Trigger Options Name : Bool1ChgTrig ( Trigger Name ) Condition : Execute when Tag changes to TRUE Data Tag : reg:Bool1 In ScriptWorX2010 create a Thread, then create a script below it Ensure that the script is stopped -  "RED TRAFFIC LIGHT" must be ON in ScriptWorX Script : NewScript Trigger Name : trg_data: Bool1ChgTrig Click the "App...

GXWorks3 GXDeveloper3 Notes

Set Device comment using Navigation Tree View -> Device-> Common Device Comment Q1. Blinking erratic display of values when choosing Controller Type : FX A1. Communication issue between the GS2110 HMI and the FX5U PLC over ethernet was resolved by the following settings : System Tree View -> Controller Setting ->CH1-> Controller Type : Melsec iQ-F , I/F : Ethernet Multi Unit type : FX5CPU, IP Address : 192.168.1.17, Port : 5562, Communication TCP Q2. When communication between the FX5U PLC and the GS2110 HMI was established the GXWorks3 Programming software was unable to go online with the PLC - gives communication error A2. The PLC connection set to "Direct" and not "Via Hub" Q3  Unable to establish simultaneous communication to FX5U PLC with SCADA (MX OPC Server ) and HMI ( GS2110 ) Need to add Melsoft  device to correspond to the HMI as shown below Q4. Functions and Function Blocks Functions :  1. Do not get i...
