S2_EvOut2 Loop 2 (slot 2) event output 2. If selected, the equation will be evaluated when the event output
is activated. This selection is available when the output 2 function the B42 in slot 2 is configured
for event, manual event only or math/logic event output only.
S2_EvOut3 Loop 2 (slot 2) event output 3. If selected, the equation will be evaluated when the event output
is activated. This selection is available when the output 3 function the B42 in slot 2 is configured
for event, manual event only or math/logic event output only.
S2_EvOut4 Loop 2 (slot 2) event output 4. If selected, the equation will be evaluated when the event output
is activated. This selection is available when the output 4 function the B42 in slot 2 is configured
for event, manual event only or math/logic event output only.
S3_EvOut2 Loop 3 (slot 3) event output 2. If selected, the equation will be evaluated when the event output
is activated. This selection is available when the output 2 function the B42 in slot 3 is configured
for event, manual event only or math/logic event output only.
S3_EvOut3 Loop 3 (slot 3) event output 3. If selected, the equation will be evaluated when the event output
is activated. This selection is available when the output 3 function the B42 in slot 3 is configured
for event, manual event only or math/logic event output only.
S3_EvOut4 Loop 3 (slot 3) event output 4. If selected, the equation will be evaluated when the event output
is activated. This selection is available when the output 4 function the B42 in slot 3 is configured
for event, manual event only or math/logic event output only.
ExpIn8-23
Expansion IO module inputs 8 to 23. If selected, the equation will be evaluated when the input
is activated. The selections are available when the expansion IO module is enabled and the
input function is set to any of the available functions except for “None”.
ExpOut32-45
Expansion IO module outputs 32 to 45. If selected, the equation will be evaluated when the
output is activated. The selections are available when the expansion IO module is enabled
and the output function is set to any of the available functions except for “None”.
NOTE:
When a trigger selection other than “Always” is made and the condition is no longer met, the previous
result of the equation will be maintained until the trigger condition is again met and a new result is
calculated. For math equations, the calculated value will be maintained. For logic and timer
equations, the previous output and timer state will be maintained. Thus, if the output is on when the
trigger condition changes to false, the output controlled by the logic equation will remain on until the
trigger condition is again met and a new output state can be determined.
The
Output selection is provided for Logic equations and is used to select the output for the equation. The
available output selections depend upon the number of loops available and the number of outputs configured
as events as well as expansion IO module configuration. The available selections can include S1_EvOut2,
S1_EvOut3, S1_EvOut4, S2_EvOut2, S2_EvOut3, S2_EvOut4, S3_EvOut2, S3_EvOut3, S3_EvOut4 and
ExpOut32 to 45 which correspond to the trigger selections above.
IMPORTANT: The output selections are common to all logic equations; therefore, multiple equations can be
assigned to the same output. If multiple equations are required for various conditions to control
a single output, make sure to configure the proper trigger for each equation so that only one
equation is active at a time. If more than one equation is active at a time, the output may toggle
on and off according to different results coming from multiple equations.
If a logic equation is set to an event output and an automatic ramp/soak program is in operation,
the event state is continuously set by the running program. If the program state and equation
result are different, the output will continuously toggle on and off. Therefore, it is recommended
that logic equations not be tied to event outputs that can also be under program control.
