DIP Switches on the RediPANEL are used to set Input/Output (I/O)
requirements. On a Remote I/O network, I/O is measured in terms of racks.
The smallest unit is a 1/4 rack.
Rack size determines the amount of space the module uses in the Input and
Output Image tables. When you select a rack size (using DIP switches),
space is reserved in the Input and Output Image Tables of your processor.
Three factors determine rack size:
•
Input/Output size
•
Flashing functions
•
Handshaking functions
Input/Output Size
Input/Output Size directly relates to the number of push buttons on the
RediPANEL module. A 16 push button module has 16 inputs and 16
outputs. A 32 push button module has 32 inputs and 32 outputs.
Flashing Function
The flashing function causes the RediPANEL outputs to flash without
additional PLC programming. If flashing is enabled, the processor allocates
additional memory in the I/O Image Table. By branching the RediPANEL
output bits with the corresponding flashing bits, the RediPANEL outputs
blink at a 0.5 second rate.
A 16 push button module requires 16 additional outputs. A 32 push button
module requires 32 additional outputs to enable the flashing function.
Handshake
The handshake function latches an input bit until it is acknowledged by the
processor. Handshaking requires an additional output bit in the Output
Image Table.
