97: The operator preceding timer 2 is OR #2, a 3-input OR, which is parameter "OR(3)".
96: The lowest input to OR #2 is operand "Cont Ip H1c On".
95: The center input to OR #2 is operand "TIMER 1".
94: The input to timer 1 is operand "Virt Op 3 On".
93: The upper input to OR #2 is operand "LATCH (S,R)".
92: There are two inputs to a latch, and the input immediately preceding the latch reset is OR #1, a 4-input OR, which
is parameter "OR(4)".
91: The lowest input to OR #1 is operand "Virt Op 3 On".
90: The input just above the lowest input to OR #1 is operand "XOR(2)".
89: The lower input to the XOR is operand "DIG ELEM 1 PKP".
88: The upper input to the XOR is operand "Virt Ip 1 On".
87: The input just below the upper input to OR #1 is operand "Virt Op 2 On".
86: The upper input to OR #1 is operand "Virt Op 1 On".
85: The last parameter is used to set the latch, and is operand "Virt Op 4 On".
The equation for virtual output 4 is:
[85] Virt Op 4 On
[86] Virt Op 1 On
[87] Virt Op 2 On
[88] Virt Ip 1 On

[89] DIG ELEM 1 PKP
[90] XOR(2)
[91] Virt Op 3 On
[92] OR(4)
[93] LATCH (S,R)
[94] Virt Op 3 On
[95] TIMER 1
[96] Cont Ip H1c On
[97] OR(3)
[98] TIMER 2
[99] = Virt Op 4
It is now possible to check that the selection of parameters will produce the required logic by converting the set of parame-
ters into a logic diagram. The result of this process is shown below, which is compared to the logic for virtual output 4 dia-
gram as a check.
