4.6 Handling 8-Channel Analog Input Modules
8-channel analog input modules operate in four difference modes, as described below. Each
mode can be set by operating the MODE and/or RANGE switches on the module’s front panel.
For details, see Chapter 3, “Individual Specifications.”
y
MODE1: A high-speed response mode with a maximum response time of 5.12 ms plus one
TRC. This mode will occupy 128 I/O points (12-bit A/D conversion data) if all the
available eight channels are used.
y
MODE2: A low-speed response mode with a maximum response time of 5.12 ms plus eight
TRCs. This mode will occupy 16 I/O points, regardless of how many channels are
used among the available eight.
y
MODE3: A high-speed response mode with a maximum response time of 5.12 ms plus one
TRC. This mode will occupy 128 I/O points (14-bit A/D conversion data) if all the
available eight channels are used.
y
MODE4: A low-speed response mode with a maximum response time of 5.12 ms plus four
TRCs. This mode will occupy 32 I/O points, regardless of how many channels are
used among the available eight.
(Note) Each TRC is a remote I/O transfer duration.
4.6.1 MODE1
setting
This mode of operation inputs analog data to the XW area and, as shown below, allows you to
use as many channels as determined by the I/O point count set in the CPU and remote I/O
station.
