1.11 Operation of the 8-CH Medium-Speed Analog
Output Module and the 8-CH Medium Speed
PWM Output Module
This section provides an explanation of the output operation of the analog output and
PWM output modules.
Output Selection When Errors Occur upon Startup
• Hold the previous value: Holds the last output value.
• Output the preset value: Outputs an arbitrarily specified output value.
Output Status
The voltage, current (analog output module), or pulse wave duty (PWM output module) is
output given the following output conditions.
• T
ransmission output: Outputs a analog or PWM corresponding to the measured
results of the input channel specified on the same unit.
The input modules that can be specified are all input modules
(excludes output modules).
• User output: When a command is received from a PC software application
(MX100 Standard Software, MXLOGGER, or the MX100/
DARWIN
API), analog or PWM output is performed according to
the received value.
After the power is turned ON and communications become available, “User Output”
is enabled. For transmission output within a unit, the output value is updated after
measurement begins.
Output on Disabled Channels
Types of Disabled Channels Output
Channels disabled through setting changes Holds the last output value when
channels were active
Channels disabled upon startup Output according to startup settings
The timing at which setting changes applied to the output module become active is as follows.
(Ex. When changing settings from transmission output within a unit to user output, the last value of
transmission output within a unit is held until the user output request is generated.)
Output Operation per Settings and Setting Changes
Status at Power ON and Output Operation
Status When Power Is Turned ON Output Operation
When the output setting is disabled Operation upon startup
For transmission output within units, Before meas. start Operation upon startup
referenced input channels disabled* Measurement start Operation upon errors
Transmission output within units Before meas. start Operation upon startup
Measurement start Transmission output
Transmission output between units Before meas. start Operation upon startup
(User output) Measurement start User output
Manual output No output request Operation upon startup
(User output) Output requested User output
Pattern output Before pattern output starts Operation upon startup
(User output) Pattern output starts User output
* Monitor “Off” on the PC software, and “Skip” on the MX100/DARWIN API.
