Processing details
• This instruction compares the clock data specified by (S1) with those specified by (S2), or the clock data specified by (S1)
with the current time data. Setting n determines the data to be compared.
When either (S1) or (S2) corresponds to any of the following conditions in comparing given or current time
data with specified clock data, the operation error (error code: 4101) or a malfunction may occurs.
• The range of the devices to be used for the index modification is specified over the range of the device
specified by (S1) or (S2).
• File registers are specified by (S1) or (S2) without a register set.
• QnU(D)(H)CPU, QnUDE(H)CPU: the serial number (first five digits) is "10102" or later
• Q00UJCPU, Q00UCPU, Q01UCPU, QnUDVCPU: Supported
(S1): Head number of the devices where the data to be compared are stored (BIN 16 bits)
(S2): Head number of the devices where the data to be compared are stored (BIN 16 bits)
n: Value of the data to be compared or the number of the stored data to be compared (BIN 16 bits)

• Comparison of given clock data
This instruction treats the clock data specified by (S1) and the clock data specified by (S2) as a normally open contact, and compares the data in accordance
with the value of n.
• Comparison of current time data
This instruction treats the clock data specified by (S1) and the current time data as a normally open contact, and compares the data in accordance with the value
of n.
This instruction treats the clock data specified by (S2) as dummy data and ignores the data.
