◆
The naming conventions for screenprint and labels of controller
terminals dier. Their mapping may be dened, for example, label
CH0-X0 = screenprint X0, label CH1-Y10 = screenprint Y10, and label
COM0 = screenprint C0, with CH0 for channel 0 and CH1 for channel
1.
◆
Terminals of CH0 may distinguish between COM0 and SS0, and
those of CH1 between COM1 and SS1. For example, CH0-Y0
corresponds to COM0, and CH0-X0 corresponds to SS0.
◆
SS0 is the common terminal for X0–X3 (high-speed inputs) of
channel 0, and SS1 is the common terminal for X4–X17 (medium-
speed inputs and general inputs) of channel 1.
◆
C0 is the common terminal for the Y0–Y7 output terminals of
channel 0, and C1 is the common terminal for the Y10–Y15 output
terminals of channel 1.
■ Wiring Precautions
1) The maximum length of the expansion cable for a high-speed I/O port must
not exceed 3.0 m.
2) In the routing process, avoid bundling expansion cables with the power cable
(of high voltage and current) and other cables that transmit strong interfering
signals. Route expansion cables separately and avoid parallel routing.
