Output Channel Data
Data that specifies the control method for output data using output channels (AO/
PWM channels).
For details of the specified actions, see the “MX100 Data Acquisition Unit User’s
Manual” (IM MX100-01E) and the “MX100 Standard Software User’s Manual” (IM-
MX180-01E).
See MXOutput structure.
The MXOutputData structure includes all channels.
It is a portion of the setup data.
It consists of the following items.
• Output type
• Value selected (when idle or during error)
• User specified output value
• Pulse interval integer multiple (PWM channels only)
The user specified output values, are specified with integers in the same manner as
the data value and span.
Output Channel Data Number
A value used to identify the output channel position.
It is an integer value between 1 and 60.
Numbers are defined.
Packet
In the case of the MX100, the communication is carried out using binary
transmission of packets.
The packet is created inside the class and transmitted according to the request
command. The response packet is received, analyzed, and the necessary data is
stored in the structure and returned.
Pulse interval integer multiple
The value that indicates the pulse width using PWM channels.
Specifies the integer multiple of the resolution of the range type.
It is an integer value between 1 and 30000.
The maximum value is defined.
Reference Alarm
Shows to which alarms the DO channels correspond. The alarm is specified using
the channel number and the alarm level.
