The module has

– Labels that identify the AutoMax DCSNet scanner and remote I/O

– A 4-character scrolling display (XXXX)

– 3 LEDs labelled NET, CLX, and OK to indicate network status, connection to the ControlLogix processor, and its own internal status

– A 9-pin D-type connector for connection to a DCS or remote I/O network

– Switches on the top of the module to set the mode of operation, number of drop-downs, and depth of drop-downs

Switches to set network type and node address

The switches on the top of the module must be used to set the network type, dropdown number, and dropdown depth before installing the module.

The two switches on the left set the dropdown depth and the two switches on the right set the dropdown number.

The following table shows how to set the switches for each mode of operation.

For example, to configure the 56AMXN/B as a DCS slave with a dropdown number of 17 and a dropdown depth of 5. set the switches from left to right to 0. 5. 1. and 7.

Any other setting is invalid and causes the module to enter the Fingerwheel Test mode. In Fingerwheel Test mode, the display shows the current switch settings.

It will not exit the thumbwheel test mode until power is removed.

In the Thumb Wheel Test Mode, the 56AMXN/B initially displays ‘Thumb Test Mode’ on the 4-character display, the

The display switch is set for 5 seconds, then the display resumes showing ‘Thumb Test Mode’.

For DCS slave operation, if the air drop number dcs-sis.com and air drop depth are individually valid but combined produce an invalid melt

If the drop number and drop depth are valid individually, but the combination produces an invalid drop number (e.g., drop number 55.), the module will display the drop number in the 4-character display,

then the module will display an error message on the 4-character display, but will not enter the thumbwheel test mode.

but will not enter the thumbwheel test mode.
