C200H High-density I/O Units are classified as C200H Special I/O Units and
have the following functions.
Dynamic I/O Mode
The High-density I/O Units (other than the C200H-ID501 and C200H-ID215)
can provide high-density I/O rather than the normal output (static output
mode) and I/O (static I/O mode). High-density I/O (dynamic output and
dynamic input modes: 128 points) is achieved by combining the I/O signals
with a strobe signal output. The High-density I/O Units require less wiring, use
a numeric display device in dynamic output mode with large number capacity,
and use keyboard switches in dynamic input mode.
High-speed Inputs
The High-density I/O Units (other than the C200H-OD501 and C200H-
OD502) also provide high-speed inputs. High-speed inputs are possible with 8
input points. This function enables accurate reading of short pulse inputs from
photomicroswitches and other devices.
C200H-OD501/OD215
By combining data signals (DATA 0 to 7 and DATA 8 to 15) with strobe signals
(STB 0 to 7/ STB 8 to 15, 128 bits (8 words) can be output to a numerical dis-
play device as shown in the following diagram.
