Open Discussion / Slc500 Indirect addressing

« on: March 10, 2017, 10:37:37 AM »

Good morning.  Is there a way to access a tag indirectly?  I am trying to access N63:[N7:0].  This is using the SLC ethernet IP driver.

Thanks,
Kenneth

Support Questions / Reading a large amount of tags

« on: December 16, 2016, 10:01:18 AM »

Good morning, I am logging fault alarms from 350 different tags.  they are located in an array(3) of 150 INT tags. 

PROGRAM:ProductionData.FaultSummary[0]
PROGRAM:ProductionData.FaultSummary[1]
PROGRAM:ProductionData.FaultSummary[2]


I currently create 3 arrays(150 long in VB) and record the status of each tag.  on the local network this takes 15 seconds to go through all 350 tags.  From home, with a DSL connection, it takes over 10 minutes. 

        ARRAY(0) = EthernetIPforCLXCom1.Read("PROGRAM:ProductionData.FaultSummary[0].GycolTankRunning")
        ARRAY(1) = EthernetIPforCLXCom1.Read("PROGRAM:ProductionData.FaultSummary[0].PreheatOvenDNS")
        ARRAY(2) = EthernetIPforCLXCom1.Read("PROGRAM:ProductionData.FaultSummary[0].PreheatBlowerDNS")
        ARRAY(3) = EthernetIPforCLXCom1.Read("PROGRAM:ProductionData.FaultSummary[0].DryOvenDNS")
        ARRAY(4) = EthernetIPforCLXCom1.Read("PROGRAM:ProductionData.FaultSummary[0].DryOvenBlowerDNS")
        ARRAY(5) = EthernetIPforCLXCom1.Read("PROGRAM:ProductionData.FaultSummary[0].PreheatBlowerTripped")
        ARRAY(6) = EthernetIPforCLXCom1.Read("PROGRAM:ProductionData.FaultSummary[0].PreheatExhaustTripped")

after recording all the data in the array files, I write all the data to a text file to import into excel.

Every thing works fine.  I am just trying to speed up the transfer, especially over my VPN.

thanks,
Kenneth
