Detection of the Device Extension
Starting from the iSMA-B-MAC36NL hardware version 2.1 and up, the device extension is
detected automatically and displayed for information in the Products field of the Workbench
platform.

LED Indicators
The device is equipped with LEDs for quick status checking and diagnostics:

•
The Power LED ON lights up (green) and then turns the power supply on.
•
The Communication LED COM1 lights up (orange) for 20 ms in the transmit state for
sending each package through the main RS485 port. As long as the device sends
packages, the Communication LED blinks continuously.
•
The Communication LED EXT lights up (orange) for 20 ms in the transmit state for sending
each package through the extension RS485 port. As long as the device sends packages,
the Communication LED blinks continuously.
•
The Communication LEDs ETH1 and ETH2 light up (orange) in the transmit or receive state
when sending/receiving each package through the particular Ethernet port. As long as the
device sends/receives packages, the Communication LEDs blink continuously.
•
The Universal Inputs LEDs U1-U16 indicate the statuses of the Universal Inputs. When the
LED is ON, the resistance value connected to the input is lower than the switching
threshold value (Dry Contact input is active).
Note: The LED also lights up when the voltage connected to the input has very low potential.
•
The Digital Inputs LEDs I1-I4 indicate the statuses of the Digital Inputs. When the LED is
ON, the Input is active (resistance value connected to the input is lower than the switching
threshold value).
