DIGITAL CHANNELS CONFIGURATION

After configuring the analog channels, it is time to configure the digital channels and relays. Just as it is in the analog
channels, on the list on the left, you can select which channel is to be configured.

Each channel can be configured as an input or an output. As an input, you can enable it or not. If it is disabled, it will not
appear as an option in the logs, alarms, in the virtual channels or even in the HMI. Once the input has been enabled, you
must provide a unique tag (name - maximum of 16 characters) for this channel. You should also provide a value to be
displayed when in "0" level (low voltage level or contact closed at the input) and another value to be indicated when in "1"
level (high voltage level or contact open at the input). These values will be shown in the channel reading. Finally, you can
optionally configure a unit (maximum 10 characters) for the input.

Digital channels - Configuring an input

From firmware version 1.10 on, it is possible to perform counting on the digital inputs. In order to do that, no special
configuration is needed; just configure digital channels as inputs. The counting values can be accessed by Modbus
registers (check the document “FieldLogger – Modbus”) and can also be copied to a virtual channel, where it can be
logged or used by the alarms, for example. When applying a new configuration in the digital channels, the all previously
collected counting values are reset to zero.
