Using the module
5.1 Using the technology module
Counting, measurement and position detection
174 Function Manual, 12/2017, A5E32009889-AG
Enable additional diagnostic interrupts
You use this parameter to specify whether diagnostic interrupts are to be triggered for
additional errors.
See the device manual for the technology module to find out which errors during operation
can trigger a diagnostic interrupt.
Diagnostics interrupts (Compact CPU)
Enable diagnostic interrupts
A Compact CPU can trigger diagnostic interrupts for certain faults if you have enabled
diagnostic interrupts. These diagnostic interrupts are processed in an interrupt OB.
You use this parameter to determine if the Compact CPU should trigger diagnostic interrupts
when a given error occurs.
See the device manual for the Compact CPU to find out which errors can trigger a diagnostic
interrupt during operation. The diagnostic interrupts are not enabled in the default setting.
Operating mode
Selection of the operating mode
for the channel
This setting defines how the channel counting and measuring functions are to be configured
and controlled.
Operating mode
Description
Operating with "Counting and
measurement" technology
object
A technology object is used for the parameter assignment of the
channel.
The related instruction in the user program provides the access to
the control and feedback interfaces of the technology module.
You specify the assignment between the technology module/channel
and technology object in the basic parameters of the technology
object.
Position input for "Motion
Control" technology object
The technology module is used for position input for a higher-level
Motion
Control controller. This operating mode effects all channels of
the technology module for TM Count and TM PosInput. Setting the
operating mode only effects the given channel of the Compact CPU.
Parameter assignment is implemented via the Device configuration
of the technology module. Parameter assignment of the encoder
signals is implemented by means of the Module parameters
(Page 175).
Manual operation (without
technology object)
The channel is configured using the parameter setting (hardware
configuration) (Page 183) of the technology module.
You have direct access to the control and feedback interface of the
channel through the user program.
Fast Mode
The technology module is used for very fast detection of the count or
position value. No control interface is available. The parameter set-
ting (hardware configuration) of the module is used for the parameter
assignment of the channel.
This operating mode is not supported by every technology module.
