The following screen is displayed: 10 10-38 Series 90-30 PLC I/O Module Specifications – 2000 GFK-0898F R0:03 HI–DEN C >S CHAN 1 LO: 00000 The display is the entry field for the low alarm limit for the displayed (in this case, 1). You can enter the desired low alarm limit lue using the numeric keys and the ± key for specifying negative lues. Enter the low alarm limit using a lue within the lid limits as listed in Table 2. After you have entered the low alarm limit lue, press the → key again to adnce to the high alarm limit display for this . The following screen is displayed at this time. R0:03 HI–DEN C >S CHAN 1 HI: 32000 The display shows the entry field for the high alarm limit for the currently displayed . You can enter positive or negative numbers (see table 2) using the ± and numeric keys. After selecting the low and high alarm limits for 1 (or the currently displayed ), you can view the next by pressing the → key. R0:03 HI–DEN C >S 2: 4–20 Edit the range, and low and high alarm limits as described for 1. All active s can be changed in this nner. Return to the initial display screen by pressing the ENT key or by pressing the ← key until the initial screen is displayed. Saved Configurations Configurations that contain a 16- Alog Current Input module can be saved to an EEPROM or MEM card and read into the at a later time. MEM cards and EEPROMs containing these configurations can be read into any Release 4 or later . Refer to Chapter 2 of the Hand-Held Programmer User’s nual for detailed infortion on the Save and Restore operations.
