2 Functions of Devices in DVP-PLC EH2/SV/EH3/SV2 series MPU: The units of the timer are 1ms, 10ms and 100ms and the counting method is counting up. When the present value in Functions of timers: the timer equals the set value, the output coil will be On. The set value should be a K value in decimal and the data register D can also be a set value. The actual set time in the timer = timing unit Ч set value There are three types of timers: 1. General purpose timer: For ES/SA series MPU: The timer executes once when the program reaches END instruction. When TMR instruction is executed, the output coil will be On when the timing reaches its target. For EH2/SV/EH3/SV2 series MPU:
The timer executes once when the program reaches TMR instruction. When TMR instruction is executed, the output coil will be On when the timing reaches its target. X0 When X0 = On, The PV in timer T0 will count up by 100ms. When the PV = SV K100, the output coil T0 T0 Y0 will be On. 10 secs When X0 = Off or the power is off, the PV in timer T0 X0 will be cleared as 0, and the output coil T0 will be SV K100 Off. T0 PV Y0 DVP-PLC Application Manual 2-16 100ms general purpose T0 ~ T199, 200 points. Can be latched by setting up parameters. T192 ~ T199 are the timers for subroutine. Total 256 points 100ms accumulative T250 ~ T255, 6 points. Fixed to be latched.
Timer T 10ms general purpose T200 ~ T239, 40 points. Can be latched by setting up parameters. 10ms accumulative T240 ~ T245, 6 points. Fixed to be latched. 1ms accumulative T246 ~ T249, 4 points. Fixed to be latched. TMR T0 K100
