Attaching to Other CCN Modules
If the machine PSIO has been connected to a CCN Network or other PIC controlled chillers
through CCN wiring, the LID can be used to view or change parameters on the other controllers.
Other PIC machines can be viewed and set points changed (if the other unit is in CCN control),
if desired from this particular LID module.
To view the other devices, move to the ATTACH TO NETWORK DEVICE table. Move the
highlight bar to any device number. Press SELECT softkey to change the bus number and
address of the module to be viewed. Press EXIT softkey to move back to the ATTACH TO
NETWORK DEVICE table. If the module number is not valid, the ‘‘COMMUNICATION
FAILURE’’ message will show and a new address number should be entered or the wiring
checked. If the model is communicating properly, the ‘‘UPLOAD IN PROGRESS’’ message will
flash and the new module can now be viewed.
Whenever there is a question regarding which CCN module the LID is currently showing,
check the device name descriptor on the upper left hand corner of the LID screen. See
Figure 23.
When the CCN device has been viewed, the ATTACH TO NETWORK DEVICE table should
now be used to attach to the PSIO that is on the machine. Move to the ATTACH TO NETWORK
DEVICE table and press the ATTACH softkey to upload the LOCAL device. The PSIO for the
19XT will now be uploaded.
