7.4.2. Checking the Sent and Received Data
Check that the correct data are sent and received.
In this document, the system data acquisition command and the number of digits displayed
past decimal point for command parameters are set to global variables in the output area
where Controller is output to Sensor Controller, and response data (the number of digits
displayed past decimal point) from Sensor Controller are checked, which are stored in global
variables in the input area.
If you change the variable values on a Watch Tab Page when Sysmac Studio is
online with CPU Unit, the devices connected to the output unit may operate
regardless of the operating mode of CPU Unit.
Always ensure safety before you change the variable values on a Watch Tab
Page when Sysmac Studio is online with CPU Unit
