E5ZN As SAP In NS-Panel
This tutorial is intended as a supplement to the original manuals for the products. Therefore, use it as a means to familiarise yourself with the product, and not as guide to complete installation. The information in the tutorial is taken from the manual (s):
SAP for E5ZN is one of many graphical objects that can be pasted into screens in NS. This simplifies both communication and artwork. This component can communicate with up to 16 E5ZN on RS485 directly from NS.
Operator panel has RS232 as standard. For shorter distances (max 50m) CJ1W-CIF11 can be used which converts from RS232 to RS485.
Figures show CJ1W-CIF11

Select the node address and baud rate (1 = 9600) with the dials in front of the control slide.
To write to the regulators CMW (Enable Comm. Writing) must be activated. The buttons for this are under \ _Basic.
In order to initialize the regulators directly from NS, one must also add the button Move to Setting Area1. It is also under \ _Basic. This button stops the valve, and one can access the parameters of signal type, control type, alarm type, etc. These are parameters that are usually set only once. Finally, return to the starting point by using the Software Reset.
