Module B875–111 Analog Input, Quick Start Test
(Original Document)
About us
Overview
The quick-start test configures a B875-111 eight-channel differential module as follows: 0—10 V input range; 0—4096 counts output format; no sample averaging. Use the following table to perform the quick-start test.
Step
Action
1
Set the module configuration switch as follows: (viewing the rear of the module when held vertically)
The following table shows switch positions and their selection.
2
Set voltage/current switches as follows:
  • All channels set for voltage inputs 10 Vdc input range
  • Place all switches (located below side access holes) to left
3
Jumper input terminal 38 to terminal 3 and terminal 39 to terminal 4 on high-density connector AS–8535-000
Note: Terminals 38–39 are a voltage reference only (4.5000 Vdc); they should not be used for any other purpose.
Note: Remove the keying tabs on high-density connector AS–8535–000 prior to installation.
4
Determine which channel and slot location are being used for this module.
5
Stop controller. Turn power off, insert module and reapply power.
6
I/O map module as B875, registers 30001—30008 binary.
7
Start controller.
8
Observe that module’s active light is illuminated.
Note: Active on steady=O.K. Active blinking=O.K., but inputs may be out of range
9
Monitor input 30001. It should indicate 1843 decimal.
Note: 4096 format/10 V range=409.6 counts/V. 409.6X4.5000 Vdc = approximately 1843 decimal
