100 Setting Up Discrete Inputs and Outputs
Ring Break Output indicator MS{node},MI13
In case of a ring break error, MI13 controls the Geo MACRO output lines and only as a safety feature.
Choose what the output state would be in a ring break situation, High (12-24V) or Low (GND) for each
individual output, depending on sinking or sourcing setup. Default MI13 equals 0, so in case of ring
break, all outputs are turned off (version 1.005 and above).

Setting up the Analog Inputs (X6 and X7)
The MACRO Geo Drive can be ordered with two analog to digital converters (option 3/4/5). These A/D
converters are 16-bit devices that are ready to be used without any software setup. Delta Tau uses the
Burr Brown ADS8343 for this circuit.
The analog signals for analog input #1 are wired in to pins 5 (ADC1+) and 9 (ADC1-) of X6, and for
analog input #2 into pins 5 (ADC2+) and 9 (ADC2-) of X7.
When selected for bipolar mode, differential inputs allow the user to apply input voltages to
±
10 volts
(20V p-p). When selected for unipolar mode, the user can apply input voltages from 0V to +10V (the
negative input ADCn- must be grounded).
To read the A/D data from the MACRO device, create the M-variable definitions to the node associated
with the MACRO device. The data is transferred into the upper 16-bits of the MACRO IO node
registers. For example, if the Geo MACRO Drive is associated with node 2, then make the following M-
variable assignment:
Unipolar
The data received is an unsigned 16-bit number scaled from 0V to +10V (0cts to 32767cts).
M3004->X:$78421,8,16,u ;ADC0 upper 16 bits of IO Node 2 word1
M3005->X:$78422,8,16,u ;ADC1 upper 16 bits of IO Node 2 word2
Bipolar
The data received is a signed 16-bit number scaled from –10V to +10V (-32767cts to 32767cts).
M3004->X:$78421,8,16,S ;ADC0 upper 16 bits of IO Node 2 word1
M3005->X:$78422,8,16,S ;ADC1 upper 16 bits of IO Node 2 word2
This example also assumes that the IO nodes are activated at both the MACRO Peripheral Device (Slave)
and at the Turbo Ultralite/UMAC (Master).
