Signal Type Direction Range Description
AnIn_Updated
BOOL Input —— True when the DigIn, AnIn and Volt signals are refreshed.
Freq_Updated
BOOL Input —— True when the Freq signal is refreshed.
Inputs – Analog Inputs
The status of analog inputs on the connectors and pins C1p11 and C1p12 is described.
Signal Type Direction Range Description
Pin _AnIn
Bus —— ——
AnIn U16 Input 0 – 32767 Analog input AD count.
Due to CAN message optimization, this value is approximated by scaling the Volt or
Ohm signals.
Volt U16 Input 0 – 5753 Analog input voltage.
Only valid when PinConfig = 0.
Volt signal is 0 when PinConfig = 1.
100 is 100 mV.
Ohm
Input 0 – 65535 Analog input resistance.
Only valid when PinConfig = 1.
Ohm signal is 0 when PinConfig = 0.
100 is 100 Ω.
Config
Bus —— ——
PinConfig U16 Output 0 – 1 Determines if the pin reads the input voltage or resistance.
0: Voltage Input
1: Resistance Input
Updated BOOL Input —— True when the AnIn and Volt or Ohm signals are refreshed.
Inputs – CAN
Diagnostic and status information about CAN communications with the I/O module is described.
The signals appear in both the Input and Output buses.
Signal Type Direction Range Description
CAN Bus —— ——
CommStatus U16 Input 1 – 8, 255 Current status of communication with the I/O module.
0: CAN message transmission is disabled.
1: Protocol Version request is being sent to the I/O module.
2: Waiting for protocol version and hardware information response.
3: The function block is sending all stored parameters to the I/O module.
4: The function block is sending all volatile parameters to the I/O module.
5: CRC request is being sent to the I/O module.
6: Waiting for CRC response.
7: The I/O module is properly configured and in the normal operational state.
8: The function block’s output pin configurations have changed. The new
configurations are being transmitted to the I/O module. Outputs are disabled.
9 – 254: Undefined.
255: Incompatible protocol or hardware. Communication to the I/O module is
stopped.
Configured BOOL
Input —— True when communication is established.
Incompat_HW BOOL
Input —— The responding hardware does not match the I/O module application layer part
number expected by the function block. No more messages are sent to the I/O
module.
