Valid Devices
Device
S1 (Source 1)
S2 (Source 2)
D1 (Destination 1)
D2 (Destination 2)
For valid device address ranges, see "Device Addresses" on page 2-1.
Special internal relays cannot be designated as D1.
When T (timer) or C (counter) is used as S2 or D2, the timer/counter current value (TC or CC) is displayed.
Make sure that the last source data determined by S1+S2 and the last destination data determined by D1+D2 are within the valid device range. If
the derived source or destination device exceeds the valid device range, a user program execution error will result, turning on special internal relay
M8004 and ERR LED on the FC6A Series MICROSmart. For user program execution errors, see "User Program Execution Errors" on page 3-10.
Source device S2 or destination device D2 does not have to be assigned. If S2 or D2 is not assigned, the source or destination device is determined
by S1 or D1 without offset.
Examples: IBMV

SOTU
I0
Source device S1 and destination device D1 determine the type of device. Source device S2 and destination device D2 are the offset values to
determine the source and destination devices.
If the value of data register D10 assigned by source device S2 is 5, the
source data is determined by adding the offset value to internal relay M10
assigned by source device S1.
If the current value of counter C5 assigned by destination device D2 is 12,
the destination is determined by adding the offset value to output Q0
assigned by destination device D1.
As a result, when input I0 is on, the ON/OFF status of internal relay M15 is moved to output Q14.
