7. CONNECTION TO FA NETWORKS
Power Mate i
I/O Link–II board
The interface connector for the I/O Link–II board of the Power Mate i is
a 5–pin connector, and two I/O Link–II cable wires are installed.
Terminating resistors are built into the I/O Link–II board. So, connect T1
with T2 by using a wire.
1 This interface is based on the three–wire system, with two
FGs omitted from the 7–pin terminal block. Perform cable
clamping and shielding with clamp fixtures.
2 When the I/O Link–II slave board is used, the interface
connector must be detached (with the communication cable
connected) before the base printed circuit board can be
installed or removed. When I/O Link–II slave board B is
used, the base printed circuit board can be installed or
removed without detaching the interface connector if the
communication cable is not disturbing.
3 On the communication cable, attach a ferrite core as close
as possible to the connector TBA (to improve noise
Compared with the I/O Link–II slave board, I/O Link–II slave board B has
improved functions. However, I/O Link–II slave board B is not
compatible with the I/O Link–II slave board. I/O Link–II slave board B
differs from the I/O Link–II slave board as described below.
(1)When the DI/DO data transfer function is used, the DI/DO size is
extended from 32 bytes/32 bytes to 128 bytes/128 bytes. (48 bytes/48
bytes when the global I/O transfer function is used) Moreover, the
allocation area is changed from X/Y addresses to R addresses.
