At the same time, iSmart will stop or just give error-warning base on the error type. Error types are show in the table below: Error code Explain Error action...
Page 47: Chapter 4: Parameter Passing
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. Even through some parameter likes “A01 = 9.99V” display in LED, in fact “9.99” stored in SMT inner system is “999”. Only in display stage, the decimal point of “9.99” added according to its physical significance. When analog variable and other function block current value passed to other function block or analog output as preset value, essentially just integers passed.
Page 48: Passing Parameter Out Of Range
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. This moment SMT will use upper limit or down limit value as its preset value.

Positive Edge Trigger - Pulse Output ( D ) A positive edge trigger (D) holds its status ON for one CPU scan time when the preceding series contact changes its state from OFF to ON. The transition from OFF to ON is called the “Positive Edge Trigger”. Negative Edge Trigger - Pulse Output ( d ) A negative edge trigger (d) holds its status ON for one CPU scan time when the preceding series contact changes its state from ON to OFF.
Page 52: Timer Instruction
Timer Instruction The iSmart includes 31 Timer coils that can be used throughout a program. T0E and T0F keep their current value after power lost if “M Keep” is active, but the other Timers’ current value is non-retentive. Each Timer has a choice of 8 operation modes, 1 for a pulse Timer and 7 for general purpose Timer. Additionally, each Timer has 6 parameters for proper configuration. The table below describes each configuration parameter and lists each compatible element for configuring Timers.
Page 53 Timer Mode 2 (ON-Delay with Reset) Mode 2 Timer is an ON-Delay with reset that will time up to a fixed preset value and stop timing when the current time is equal to the pre-set value. Additionally, the Timer current value will be kept when Timer is disabled. In the example below, the Timer will stop timing when it reaches its preset value of 5 seconds.
Page 54 Timer Mode 4 (OFF-Delay) Mode 4 Timer is an OFF-Delay with reset that will time up to a fixed preset value and stop timing when the current time is equal to the pre-set value. Additionally, the Timer current value will reset to zero when Timer is disabled. In the example below, the timer reset input is Input I01. The timer status bit T01 will turn ON only after its rung transitions from true to false.
Page 55 Timer Mode 6 (FLASH with Reset) Mode 6 Timer is a Flash timer with reset that will time up to a fixed preset value and then change the state of its status bit. Additionally, the Timer current value will reset to zero when Timer is disabled. In the example below, the timer reset input is Input I01. Timer status bit T01will be ON immediately when its rung is true and begin its timing sequence.
Page 56 Timer Mode 8 (second chronograph mode Timer mode 8 is stopwatch mode with reset control and pause control. When control condition from OFF to ON, The timer starts ticking; When the timer reaches the preset value, the output coil will change its state, and the current value of the timer will be displayed as the preset value, and the timing will not continue. When the reset control is effective, the current value of the timer and the output coil will be reset to 0.
Page 57 Counter Instructions The iSmart includes 31 counters that can be used throughout a program. Each counter has a choice of 9 operation modes, 1 for pulse counter, 6 for general purpose counting and 2 for high speed counting. Additionally, each counter has 6 parameters for proper configuration. The tables below describe each configuration parameter and lists each compatible memory type for configuring counters.
Page 58 Counter Mode 2 (Overtaking, Non-Retentive) Mode 4 Timer is an OFF-Delay with reset that will time up to a fixed preset Mode 2 Counter will count up to a fixed preset value and continue counting even reach the preset value, but it will not count when the current value equals 0 in counting-down mode. Additionally, the current count value is non-retentive and will reset to init value on a powering up to the smart relay or switching between RUN and STOP.
Page 59 Counter Mode 5 (Overtaking, Up-Down Count, Non-Retentive) Mode 5 Counter’s operation is similar to Mode 2, overtaking and non-retentive. Its status bit will be ON when the counter current value is not less than its preset value and will be OFF when the current value is less than its preset value. The Mode 5 Counter will count up to a fixed preset value and continue counting even reach the preset value.
Page 60 High Speed Counters (DC Version Only) The DC powered version smart relays include two 1 KHz high speed inputs on terminal I01 and I02.

Page 143 IO Link Function Function description: Up to 8 iSmart units can be linked together as the IO Link Network. Each unit runs their own logic program; the ON/OFF state of input, output points, and Auxiliary Coils in each one can be assigned to “W Table”, see the next page for more information. There must be one master (ID=00) and several slaves with the continuous ID number starting from 01 in the network. The master one does not perform the IO Link function to the units with the ID behind the first broken number once the ID numbers are not continuous. For example, the slaves’ ID are 01, 02, 04 and 05, the master just can recognize only two Slave, ID 01 and 02, the ID 04 and 05 will be skipped.

Page 152 AC inductive load needs to connect Surge absorber in parallel way to absorb the noise if the iSmart output terminal is the relay type. DC inductive load needs parallel connect commute diode if the iSmart output terminal is the relay type. The specification of inverse voltage for commute diode should be more than 5~10 times the rated current of the circuit, and the specification of positive current of diode should be more than load current. Inductive load needs parallel connect commute diode if the iSmart output is transistor. Digital IO module and Analog module both have indicator light in orange color. The state of indicator light in different operation state is the same. The state of indicator light is shown below.
