SELOGIC Control Equation Programming
SEL-311 and SEL-351 Series Users
Modify your SELOGIC control equations to simulate the process. While you
may be unable to change the state of a discrete input easily, such as IN201,
you can substitute a logical 1 or logical 0 in your logic to simulate the
operation of IN201 and observe the results.
Use the SER capabilities of the relay to monitor and record inputs, internal
calculations, and outputs. For operations that occur very quickly, use the SER
during testing to reconstruct the operation of your logic.
Use the MET PMV and MET AMV commands to display the contents of the
protection or automation math variables.
SEL-311 and SEL-351 Series Users
You can convert logic that you have used in SEL-311 series relays and
SEL-351 series relays to logic for the SEL-400 series. In the SEL-300 series
relays, SEL
OGIC control equation programming is restricted to equations
where the left side value, LVALUE, is fixed. The relay uses primarily free-
form programming. Table 14.28 shows comparable features between the
SEL-311 series relays and the SEL-400 series. Convert programming into
either the free-form style or the fixed style of SEL
OGIC control equations, or
whatever combination you deem appropriate for your application.
Table 14.29 shows the SEL-400 series Boolean operators compared to the
operators used in the SEL-300 series relays.
