=============
This is series tutorial for industrial automation and Delta PLC Programming Beginner to Advanced
in ISPSoft.
ISPSoft is the latest program development tool for Delta's programmable logic controllers (PLC) that complies with the IEC 61131-3 standard to integrate multiple tasks for project management. Customers can use standard PLCopen® function blocks, as well as Delta's self-developed function blocks to easily achieve different control requirements. ISPSoft offers users an efficient and convenient development environment, and is suitable for both small and complex control systems.
Timer, T, in delta ISP Soft timer and command is TMR
Here is 3 types of timer-based on time in millisecond
100 ms Timer = 1000ms = 1 sec
1ms = 1/1000
100 = (1x100)/1000
So for a 100ms timer (millisecond), the multiplying factor is 10
10 ms Timer = 1000ms = 1 sec
1ms = 1/1000
10 = (1x10)/1000
So for 10 ms timer (millisecond), the timer multiplying factor is 100
1 ms Timer = 1000ms = 1 sec
1ms = 1/1000
1 = (1x1)/1000
So for a 1 ms timer (millisecond), the timer multiplying factor is 1000
c) Device list of ISP Soft (X,Y, M,T,D)
X = Digital input
Y = Digital output
M = Auxiliary relay or memory
D = Data Register for store value,
T = Timer
Timer instruction in Delta ISP Soft
Today We will use, TMR, MUL, instruction
ADD, SUB
and use of Data Register,
Practical
Assume that we have 3 outputs,
Output1 = will be start when push_on is press
Output2 = active after 5 sec (Timer=1) 100ms
Output3 = active after 10 sec (Timer=2) 100ms
And 2 inputs, Input1 = for push_on
Input2 = push_off
So we finished, creating a local variable
MUL = for Multiplication any 2 number
Here 5 = for 5seceond time delay
And 10 is the Multiplying factor
