Are DIO bits numbered: bit 0 to 7 bit.
The CML00 extension is most significant bits (MSB)
To example:
-
“hex” F0 to answer “binary” 11110000,
-
“hex” AA to answer “binary” 10101010
3.5.1 Digital Inputs
The digital inputs DI1 ... DI8 are standard TTL inputs
The inputs can be read by SNMP network commands (crate.signal.digitalInput OID)
To example:
get one byte:
•
C:\>snmpget -v 2c -m +WIENER-CRATE-MIB -c guru -t 0.01 -r 10 192.168.91.234
digitalInput.0
WIENER-CRATE-MIB::digitalInput.0 = BITS: FF d0(0) d1(1) d2(2) d3(3) d4(4) d5(5)
d6(6) d7(7)
3.5.2 Digital Outputs
The digital outputs DO1 ... DO8 are push/pull 5V CMOS TTL outputs
The outputs can be set/reset by SNMP network commands (crate.signal.digitalOutput OID)
To example:
set one bit:
•
C:\ >snmpset -v 2c -m +WIENER-CRATE-MIB -c guru -t 0.01 -r 10 192.168.91.234
digitalOutput.0 x d0
WIENER-CRATE-MIB::digitalOutput.0 = BITS: D0 d0(0) d1(1) d3(3)
set one byte:
•
C:\>snmpset -v 2c -m +WIENER-CRATE-MIB -c guru -t 0.01 -r 10 192.168.91.234
digitalOutput.0 x: F0
WIENER-CRATE-MIB::digitalOutput.0 = BITS: F0 d0(0) d1(1) d2(2) d3(3)
get one byte:
•
C:\>snmpget -v 2c -m +WIENER-CRATE-MIB -c guru -t 0.01 -r 10 192.168.91.234
digitalOutput.0
WIENER-CRATE-MIB::digitalOutput.0 = BITS: F0 d0(0) d1(1) d2(2) d3(3)
3.6 Additional Control & Meassurement Signals
Additional analog inputs are available at connector X1 (assembled on request) see

3.6.1 Analog Inputs
The analog inputs U4 … U7 have differential inputs (0-3V operating range)
The data can be accessed via SNMP (crate.signal.analogMeasurementVoltage OID)
