11 1.5.3 Device function specification PLC Function Application Auxiliary relay (M) There are many auxiliary relays in PLC, they can be divided into general, power off keep and special three categories, the address code of auxiliary relay is according to decimal code. Specific configurations are as follows: General Power off keep Special 160 points,m0~m points,m160~m points,m8000~m8079 General auxiliary relay The function of general purpose auxiliary relay is similar to intermediate relay in electric control circuit, the general purpose auxiliary relay can be used as intermediate storage and signal transformation. Auxiliary relay can be driven by the contact of soft components within the PLC. Auxiliary relays have a myriad of normally open contacts and normally closed contacts can be unlimited used, but can't drive external loads directly. Power off keep auxiliary relay Power off when the PLC running, the state of power off keep auxiliary relay will be saved in EEPOM of inverter before inverter thoroughly losing electricity. Then power on, power off keep auxiliary relay which maintain the state will continue to be used. Special auxiliary relay Special auxiliary relay is an internal relay whose application is already determined in the PLC function. Therefore, undefined special auxiliary relay do not use. Please refer to Section1.5.4 for detailed. Timer (T) The timer is equal to time relay in the electrical control circuit, it can be applied in the program to delay control. The address code of timer is according to decimal code. The PLC function has only one timer, Timing for timing upwards. egular period is 100ms; measurement range is from 0 to s. There are eight points that is T0 to T7 which address code is according to decimal code. Outside of own number memory, timer also have a set value register and a current value register. The program timing setting is stored to the current value register, timing register records at the current value of these registers are hexadecimal storage. eal time is the set value multiply by time unit. When the count value is equal to the set value, the timer output contact action. Timer can use the decimal constants (k) as the setting value, can also use the data register (d) indirect setting. Counter (C) Counter is used to count. There is only one 16-bit increased counter in built-in PLC; measurement range is from 0 to There are eight points that is C0 to C7. The current value register and the set value register are the 16-bit binary registers; the set value range is from 0 to

12 PLC Function Application X10 X10 X11 C0 ST C0 C0 K10 X11 C0 current value C0, As indicated in Figure, X11 ON->OFF, C0 current value increases by 1 at a time, and when the count reached K10, C0-contact action, output. Then X1 triggering again, C0 also won't accumulate and kept in the K10.When the power supply is OK, the current value register of the counter with memory, so before the counter start counting you should reset the current value register with ST instruction. Data register Data register is divided into general data register and special data register. General data register Once written data in the general data register, as long as no longer write other data, the general data register is not changed. If PLC run command OFF or power off, the data will be cleared. The data register which used to Power off keep can maintain its data. Special data register Special data register is an internal relay whose application is already determined in the PLC function. Please refer to Section1.5.5 for detailed Special auxiliary relay function specification Special auxiliary relay is an internal relay whose application is already determined in the PLC function. Therefore, undefined special auxiliary relay do not use.
