Cyclic Data about the Chain
Short Name
Data Format
Description
Order mismatch
1/0
The order of devices in the chain does not match the configuration
No ISD data detected
1/0
No (or corrupted) ISD data being transmitted (being received by diagnostic device)
Incompatible device
1/0
The chain or a unit in the chain has data but not ISD data
ISD detected not configured
1/0
ISD data detected on inputs that are not configured as ISD input
Terminator missing
1/0
Terminator plug not present (or inputs to first device low)
Actuator not taught
1/0
Not applicable
Wrong actuator detected
1/0
Not applicable
Internal unit error
1/0
A unit in the chain has an internal error
Output fault detected
1/0
A unit in the chain has an output fault and will turn off after the switch off delay period
Individual Unit Data - Flags

Description
Actuator detected
1/0
Not applicable
Wrong actuator detected/Button
armed
1/0
E-stop button is in the run state
Sensor not paired
1/0
Not applicable
Output 1
1/0
Output 1 is on
Output 2
1/0
Output 2 is on
Marginal range/Button armed
1/0
E-stop button is in the run state
Input 1
1/0
ISD device input 1 is on
Input 2
1/0
ISD device input 2 is on
Local reset expected
1/0
An ISD device with the latch feature requires a reset
Operating voltage warning
1/0
Voltage to the ISD device is at the limit of specifications
ISD data error
1/0
ISD error bit, corrupted data was received from the SI-RF ISD chain of switches.
Safety input fault
1/0
The system detected a fault on a safety input of an ISD device, power cycle required
Output error
1/0
ISD Device detects an output short to voltage or ground. This starts the "switch-off timer"
counter.
Operating voltage error
1/0
Voltage to the ISD Device is above (over 30 V DC) or below (less than 19.2 V DC) limit of range.
Power cycle required
1/0
ISD Device detects a fault, a power cycled required.
Individual Unit Data - Configuration
Short Name
Data Format
Description
Local reset unit
1/0
The ISD Device includes the latch feature
High coding level
1/0
Not applicable
Cascadable
1/0
The ISD Device includes the cascade feature Note: This will always be true for Emergency Stop
models with ISD.
Fault tolerant outputs
1/0
Indicates that the ISD Device includes the fault tolerant output feature where output faults cause a
20 minute off delay/fault delay. Note: This will always be true for Emergency Stop models with
ISD.
