B–64193EN/01
140
In the case of the Series 20i, four manual pulse generators are sometimes
connected. However, only up to three manual pulse generators can be
connected to the separate wiring I/O module or to the control panel I/O
module. For this reason, in the case of the Series 20i, two separate wiring
I/O modules or control panel I/O modules having a manual pulse
generator interface are used. Even in a combination of two of these
modules having the same specifications, the connection is possible even
in a combination of one of each of these modules.
Connect these two modules by I/O–Link, and connect the three manual
pulse generators to the module close to the controller, and the remaining
manual pulse generator to the module next closest to the controller.
NOTE
This method of use is applied only in the case of the Series
20i, and cannot be used on other machine types.
Example)
The following describes an example of input signal assignments when
a control panel I/O module (A20B–2002–0470) and a separate wiring
module (A20B–2002–0520) are used.
D Assign 16 bytes from x0008 as the start of the input signal on
A20B–2002–0470 and 16 bytes from x0024 as the start of the input
signal on A20B–2002–0520.
