10.8. Logic Input Functions & Status
– AI’n’, IN
10.8.1. AI Assign input
‘n’
[ Index 0x2074 and 0x2076 ]
This command reads / setup the function of the logical inputs. The values for ‘n’ are 0 or 1.
Master (PC / SPS) sends Slave (DAD 141.1) responds Meaning
AI_1 I1:+00000 Reading Input 1: no function
AI_1_10 OK Setup accepted
AI_1 I1:+00010 Input 1: display set to ‘Peak to Peak’ value
The 2 logic inputs ‘n’ can be used for the different functions:
00 - Input "n" has no function
01 - Input "n" acts as Zero button
02 - Input "n" acts as Tare button
03 - Input "n" acts as Up arrow button
04 - Input "n" acts as Down arrow button
05 - Input "n" starts the Trigger function
06 - Input "n" displays the Average value
07 - Input "n" displays the Peak value (maximum)
08 - Input "n" deletes the Peak value (maximum)
09 - Input "n" displays the Hold value
10 - Input "n" displays the Peak to Peak value
11 - Input "n" displays the Valley value (minimum)
12 - Input "n" disables the buttons
13 - Input "n" stores the actual weight (Hold value)
14 - Input "n" tares the displays and deletes all other values
15 - Input "n" turn off display
10.8.2. IN Read status of the logic inputs [ Index 0x210C ]
This command reads the status of the digital inputs.
Master (PC / SPS) sends Slave (DAD 141.1) responds Meaning
IN I:0000 Reading: Input 0 or 1 inactive
IN I:0001 Reading: Input 0 active
IN I:0010 Reading: Input 1 active
IN I:0011 Reading: Input 0 and 1 active
The status response is in the form of a four digit code where 0 = false and 1 = true (inputs are active ‘high’).
The least significant bit corresponding to Input 0.
