Chapter 2 Installation Mounting DIN-rail Mounting The iSmart relay should always be mounted vertically. Press the slots on the back of the iSmart and expansion module plug CONNECTOR onto the rail until the plastic clamps hold the rails in place. Then connect the expansion module and CONNECTOR with the Master (press the PRESS-BUTTON simultaneously)
Page 27 Chapter 2 Installation It is recommended to apply a DIN-rail end clamp to hold the iSmart in place. Direct Mounting Use M4 screws to direct mount the iSmart as shown. For direct installation of the expansion module, slide the expansion module and connect with the Master after the Master is fixed.
Page 28: Wiring
Chapter 2 Installation Wiring WARNING: The I/O signal cables should not be routed parallel to the power cable, or in the same cable trays to avoid the signal interference. To avoid a short circuit on the load side, it is recommended to connect a fuse between each output terminals and loads.

Page 74 Chapter 4: Parameter passing In the iSmart, 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. iSmart inner data type All the data stored in SMT inner system are integer.
Page 75 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 76 Chapter 4: Parameter passing...
Page 77: 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 78 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.

So, current value won’t be initiate value when Counter powers up but be the value when it powering down. Mode 3 Counter will count up to a fixed preset value and stop counting at that value or stop counting when its current value is 0 if it’s configured as down counter.
