Chapter 6 AOP Controller Tags
EMD Tags
Table 11 lists the tags that are used by the EMD module with delayed outputs.
Table 11 - EMD Relay Tags (Tag name prefix: ENETRname:I.Relayx_GSR_EMD.)
Name Data Type Definition
SingleWireSafetyIn BOOL Single Wire Safety Input Status – Indicates whether the Single Wire Safety input (L12) is ON or OFF.
0 = The Single Wire Safety input signal is OFF.
1 = The Single Wire Safety input signal is ON.
B1State BOOL B1 Status – Only when the Safety Output is ON, this tag indicates whether input B1 is ON (connected to 24V DC or to B2) or OFF. When
the SafetyOutput tag is 0, B1 State is 0.
0 = The input is OFF.
1 = The input is ON.
SafetyOutput BOOL Safety Output Status – Indicates whether the safety output channels are ON or OFF.
0 = The safety output channels are OFF.
1 = The safety input channels are ON.
Recoverable_Fault BOOL Recoverable Fault Status – Toggles ON (1) for one scan when the EMD has detected an unexpected operation.
0 = No fault
1 = Fault
NonRecoverable_Fault BOOL Nonrecoverable Fault Status – Toggles ON (1) for one scan when the EMD has detected unexpected internal operation or failed a pulse
check. See
NonRecoverableFault_A and NonRecoverableFault_B for details.
0 = No fault
1 = Fault
NonRecoverableFault_A SINT Nonrecoverable Fault Processor A – Indicates that Safety Processor A has recorded a nonrecoverable fault. See Table 12 on page 53 for
a list of nonrecoverable fault codes.
NonRecoverableFault_B SINT Nonrecoverable Fault Processor B – Indicates that Safety Processor B has recorded a nonrecoverable fault. See Table 12 on page 53 for
a list of nonrecoverable fault codes.
Input_Retrigger BOOL Input Retrigger – Indicates whether a retrigger event occurred when the EMD is configured for non-retriggerable OFF-delay. If the
SWS input at terminal L12 turns ON during the timing period, this tag is set to 1 and the PWR/Fault indicator is green with flashing red
4X. Turn the SWS input OFF during the timing cycle to clear the fault condition.
0 = No fault
1 = Retrigger event occurred.
InvalidSwitchSetting BOOL Invalid Switch Setting – Indicates that either the Range or Time (or both) switch settings have been changed after configuration. The
Recoverable Fault tag changes from 0 to 1 for one scan and then the InvalidSwitchSetting value changes from 0 to 1 and remain at 1
until the switches are returned to their original configured values. The PWR/Fault indicator is green with flashing red 2X when this tag
has a value of 1.
0 = No changes
1 = One or both switches have changed
B1_B2_Setting_Change BOOL While the Safety Output tag is On, this tag indicates whether the connection between terminals B1 and B2 has changed from its
original configuration.
Example: The EMD is configured for OFF-delay with B1/B2 connected (retriggerable). If the B1/B2 connection opens while the safety
output is ON, the following events happen:
1. The Recoverable Fault tag changes from 0 to 1.
2. The B1 State tag changes from 1 to 0.
3. The B1_B2_Setting_Change tag changes from 0 to 1.
4. The Recoverable Fault tag changes back from 1 to 0.
5. The PWR/Fault indicator is green with flashing red 3X.
If the B1/B2 connection is remade while the safety output is ON, the same steps happen with the values reversed, and the PWR/Fault
indicator changes to solid green.
When the SafetyOutput tag is 0, the B1_B2_Setting_Change tag has a value of 0.
0 = Connection has not changed.
1 = Connection changed.
