Analog Input
Analog input is read in 16-bit word units Each channel value is stored in sub index of the object 6401h.
Data is not updated unless "PDO transmission enabled/disabled" (6423h) is set to 1 (enabled).
Analog Output
Analog output is written by the unit of 16 bit word. Output bit is stored in sub index of the object 6411h. It is switched to fallback mode when an error occurs.
Analog I/O Settings - Common Objects (Model: EXM-AMI2HT, EXM-AMO1HT, EXM-AMM3HT and EXM-ALM3LT)
The following describes CANopen objects used in analog I/O for EX modules. Sub index number "n" (2 or more) is determined by the position of the module connected to HTB and the object that is used.
For details on the relationship between sub index "n" and attached position of EX module, refer to the following.
30.7.6.15 Sub Index
EX modules that support analog have different setup objects between models. The following common values are used in all channel and registries.
