Communication 2 Data Access Error for Alias /*S:0 Param2*/,

Controller /*S:0 Param3*/, Address is /*S:0

Param4*/, Communication Flag is /*S:0 Param1*/

The terminal is having trouble reading the external

tag at this controller and address.

Check that the communication network cable is

connected.

If new ladder logic is downloading to the controller,

you could see this message. After the download,

communication should run normally.

Verify you have good communication to the

controller. If a remote device not responding alert

was present, then all external tags being actively

scanned will generate this alert.

Is the address configured in the controller? If so,

make sure all addresses of external tags to this

controller are configured at the controller. If one

address is outside of the range, a block of

addresses might show this condition. If the address

is configured as write only at the controller, this

address cannot be read. Set this external tag as

write only and remove panel devices from your

application that want to display data from this

external tag.

Communication 3 Communication Server Error. Contact technical support providing this data.
