Mapping the Interlocks
The following example demonstrates single pin addressing.
Input designation 1 (EXT_IN1) = DIGITAL_IN 0x (pin #2) = DIGITAL_IN 0x2.
Input designation 23 (EXT_IN23) = DIGITAL_IN 0x (pin #24) = DIGITAL_IN
0x800000.
Output designation 0 (DRV_OUT0) = DIGITAL_OUT 0x (pin #31) = DIGITAL_OUT
0x1.
Output designation 19 (DRV_OUT19) = DIGITAL_OUT 0x (pin # 50) =
DIGITAL_OUT 0x80000.
The following example demonstrates multiple pin addressing.
Input designation 14-21 = NUMERIC_IN 0x (pin #15-22) = NUMERIC_IN 0x3fc000
where 3 = 2 + 1
f = 15 = 8 + 4 + 2 + 1
c = 12 = 8 + 4
0 = empty block
0 = empty block
0 = empty block
In the following example, if a slot valve is closed, the robot will not attempt to
extend at a station.
The following is assumed:
•
The slot valve sensor at Station 2 will have the assigned name
STN_2_SLOT.
•
Slot valve sensor is a switch which is closed when the valve is open. The
switch is wired between a EXT_IN0 pin 1 and GND (pin 29).
1.
Establish serial communication.
NOTE:
DIO mode and CDM mode do not support the mapping functionality.
