4-40
c) I/O Data Format
The following items can be set to define the I/O data format. There is, however, gen-
erally no need to change these settings, except for the mode setting, because the
default settings can be used for most normal applications.
(1) Mode Setting
(a) Analog Output Module ( ±10 V, 4 channels)
The data format can be set to either of the following formats.
• ±2000 mode: ±10 V / -2000 to +2000
• 0 to 4000 mode: ±10 V / 0 to +4000
The MEMOSOFT is set by default to the ±2000 mode.
(b) Analog Output Module (0 -10 V, 4 channels)
Only the 0 to 4000 mode can be used as the data format.
• 0 to 4000 mode: 0 to 10 V / 0 to +4000
The MEMOSOFT is set by default to the 0 to 4000 mode.
(c) Analog Output Module (0 -5 V, 4 channels)
Only the 0 to 4000 mode can be used as the data format.
• 0 to 4000 mode: 0 to 5 V / 0 to +4000
The MEMOSOFT is set by default to the 0 to 4000 mode.
(d) Analog Output Module (4 to 20 mA, 4 channels)
Only the 0 to 4000 mode can be used as the data format.
• 0 to 4000 mode: 4 to 20 mA / 0 to +4000
The MEMOSOFT is set by default to the 0 to 4000 mode.
(2) Service Scan: Normal/High-speed
Two types of service scans are available: normal and high-speed. A service
scan is recommended when using the high-speed segment function. The I/O
module is activated before the ladder decoding of the high-speed segments.
The I/Os that are processed in synchronization with the high-speed scan are
called High-speed Segment I/Os.
The MEMOSOFT is set by default to “NORMAL.”
(3) Output Status When CPU Stops
The data that is output when the CPU Module changes from a running status to
a stopped status can be specified. Any of the following settings is possible.
Open Output: All output terminals are opened.
Hold Output: The output values just prior to stopping.
Set by User: Preset values are output.
The MEMOSOFT is set by default to “OPEN OUTPUT.”
d) User Set Value
The data that is output when the CPU Module stops (when “SET BY USER” is spec-
ified for the timeout output) can be set. The MEMOSOFT is set by default to all
zeros.
