3.4.1.4 Handwheel I/O
On each 2416 EL input/output module two special inputs for hand-
wheel connections are provided. The inputs are located on bit 23 and
24 of the third byte of each 2416 EL module. They are designed for
24 V encoder handwheels meeting the following specifications.
Special use of bits 23 and 24 of the 3rd input byte
When connecting handwheels to the described inputs only use 24 V
encoder handwheels. When no 24V handwheel is connected, the two
inputs can be used in the same way as the other inputs of the 2416 EL
module.
