EZTouch I/O
Jr.
37 / 52
Please Note: Since the Panel Editor is a common programming platform for all the
models offered by the AVG
EZTouch I/O
family, it may allow you to include 128 Inputs
(I), 128 Output (O), 64 input Registers (IR) and 64 Output Registers (OR) in the main
logic. However, the
EZTouch I/O
Jr. only physically supports 8 discrete inputs and 6
discrete outputs; hence you may use I1-I24 and O1-O16 while programming the
same. The remaining O bits may be used as “Scratch bits.” Similarly, only IR1-IR4
and OR1-OR4 should be used to address the I/O Registers, while the rest of the
Output Registers may be used as “Scratch Registers.” Although there are 20
System Registers (SR) and 20 System Discretes (SD) available in the programming
software, only SR1-9, SD1-4 and SD9 are used by the
EZTouch I/O
Jr.
Mapping Conventions
Discrete Inputs/Outputs
Discrete Inputs
Discrete Inputs are denoted using an “I” pre-fix (e.g. I1, I4, etc.). The maximum
number of physical Inputs available in an
EZTouch I/O
Jr. is 8. Hence, you may
only use I1 – I8 (or I1 – I16, depending on the model) in your main logic.
Discrete inputs are Read only type.
Note: All the discrete type EZ Inputs are mapped to Discrete Input bits. In the
example above, the output bit O1 will be turned on when input I1 allows
power through the rung.
