Operation Of The Recording Function When Configuring Multiple Modules - Mitsubishi Electric MELSEC iQ-R Series User Manual

Operation of the recording function when configuring multiple
modules
The following shows the operation of the recording function when configuring multiple modules.
Main and sub modules
When using multiple modules, configure the main module that controls all recording for the modules and a sub module that
operates in synchronization with the main module.
One main module must be set.
After switching a CPU module to RUN, the main module and a sub module with recording target data start recording.
However, a sub module without recording target data does not start recording.
The following table shows the operations of the main module and a sub module.
Type
Main
Sub
*1 Can be set when using a camera recorder module.
*2 A recorder module with the firmware version '04' or later is required.
■Configuration in which a recorder module is included
In this configuration, a recorder module is always set as the main module. Set a camera recorder module as a sub module.
■Configuration in which only a camera recorder module is included
In this configuration, set a camera recorder module as the main module and another camera recorder module as a sub
module.
If no module is set as the main one or multiple modules are set as the main ones, an error occurs in a CPU module.
Devices and labels are accumulated in a module set as the main one.
Operating status after starting the recording function
After starting the recording function, the operating status switches to 'operating' when the operating status for a target
recording setting switches to 'preparing,' the main module and all sub modules with recording target data complete
preparation and start operating.
If a sub module cannot start operating, the operating status switches to 'operating' when the main module and the other sub
modules start operating.
For the operating status of the recording function, refer to the following:
Page 63 Operating status
For the operation to start the recording function, refer to the following:
Page 65 Start
Operating status after stopping the recording function
After stopping the recording function, the operating status switches to 'stopped' when the main module and all sub modules
with recording target data stop operating.
However, when the operating status is 'file saving trigger satisfied' or 'saving,' it switches to 'stopped' after saving is completed
for the main module and all sub modules with recording target data.
For the operating status of the recording function, refer to the following:
Page 63 Operating status
For the operation to stop the recording function, refer to the following:
Page 66 Stop
Description
Controls all recording for a recorder module/camera recorder module, determines whether a recording startup trigger
or file saving trigger is satisfied, accumulates devices and labels, and receives and accumulates video data
A recorder module is always set as the main module.
Performs recording in synchronization with the main module.
A camera recorder module can be set as a sub module, and it receives and accumulates video data only.
