Page 69: Sg2 Inner Data Type
Chapter 4: Parameter passing In SG2, almost all the function block can use other function block’s current value as its preset value. This process we called data transmission. This chapter will describe some regulation about data transmission. SG2 inner data type All the data stored in SG2 inner system are integer.
Page 70 Chapter 4: Parameter passing Example2: MD01 current value passing to other function block as preset value: When B006(MD01)=430, MD01’s inner value 430 is passed to other function block as preset value. Passing to AQ01 automatically as 4.30V, Passing to B001(G01) automatically as 4.30, Passing to B002(T01 time base is 0.01s) automatically as 4.30s, Passing to B003(T02 time base is 0.1s) automatically as 43.0s, Passing to B004(T03 time base is 1s) automatically as 430s, Passing to B005(C01) automatically as 430:...
Page 71: Passing Parameter Out Of Range
Chapter 4: Parameter passing Passing parameter out of range MD current value data range is -32768~32767, T preset value data range is 0~9999. If MD current value is passed to T as preset value, obviously sometimes MD current may greater T preset value upper limit, or less than T preset value down limit.
Page 72 Chapter 4: Parameter passing Example2: When AT01=-100.0, AT01’s inner value -1000 is passed to other function block as preset value. Passing to B002(T01 time base is 0.01s) as preset value. -1000 is less than lower limit of T01 0, so automatically as 00.00; Passing to B003(C01) as preset value.

Since auxiliary relays are internal elements within the CPU, they can be programmed as digital inputs (contacts) or digital outputs (coils).
