Tag addressing in citect scada

Hi Guys,

currently I am working on Citect Scada project where i am using AB plc to connect with SCADA.

now, i am finding problem with addressing tags in SCADA with AB plc tags. i don't know how to find out correct addresses of general bit (general tags created during program) in AB plc and how to implement in SCADA.

if any one know the exact way to connect AB plc with Citect Scada pls let me know.

thanks in advance.

Citect can only access controller scoped tags.
for the tag address structure see the driver help for CLX in the Citect project explorer help.
Some basics are
for bit tags replace the "." with "/"
for Array tags replace the "[]" with"{}"

Is this a working project or are you starting from scratch?

If Machine_Running is a controller level tag in the PLC then the Citect Address will be Machine_Running of type DIGITAL.

Are you trying to access IO directly?

You cannot create a structure in Citect like you can in ControlLogix. You need to drill down to the bottom of the IO structure and assign that a DIGITAL, LONG or REAL Citect data type depending on what sort IO you are trying to read.

Hi vazgen
you have to create 2 i/o device for 2 ADAM 4017+ ,one on for IoDev_4017_1 and another one for IoDev_4017_2 ,address are Ai0 -Ai7 for Each ADAM you have to select i/o device name separately for each variable.now you have 16 Analogue input 8 for IoDev_4017_1 from Ai0 - Ai7 and 8 for IoDev_4017_2 from Ai0 - Ai7 .
