Changing either the Zone Name or the Zone Description is performed in the same manner, and does not require the Supervisor to be logged on. Simple touch the text box, the keypad will popup and you can enter the new text. The operational mode of the SEC 3500 OI does not stop and is not affected. Changes are stored permanently in the OI after about ten minutes or so. To make them remain permanent immediately, reboot the OI (See the Basic Operator’s Manual or the Startup Basics Guide).
5.0 Deleting/Removing Devices
Adding devices to the network is as easy as connecting a new one to the Modbus network, and if necessary, changing the device & zone IDs. However deleting them is another matter. If you perform the deletion without removing the device form the Modbus network, it will be re-detected and auto-added next time it is scanned. Therefore, you must first remove the device from the Modbus network and allow it to be declared off-line first. You must be logged on as the Supervisor to perform this operation, then proceed to the associated device summary screen (Sensor or Relay Module) and touch the “Delete” button as show below:
The OI will transition from normal operation through shutting down Modbus communication/measurement (as illustrated previously in section 4.0) and finally to the Device Deletion Screen as shown on the following page:
