uPLC Registers

Parameter	Description	Data type
8674	Constant value = -1	int16
8675	Constant value = 0	int16
8676	Constant value = 1	int16
8677	Constant value = 2	int16
8678	Constant value = 10	int16
8679	Constant value = 100	int16
8680	Constant value = 1000	int16
8681	Constant value = 1024	int16
8682	Constant value = 4096	int16
8683-8700	Free parameters area	int16
8026	PLC activation: 0→ program not executed, 1→ program executed	int16
8027	Number of valid instruction in the PLC	uint16
8028	First timer, every 6 msec, if 8028 is not 0, it is decremented, if it is equal to 0, the bit 0 of parameter 8671 is set to 1	int16
8029	Second timer, very 6 msec, , if 8029 is not 0, it is decremented, if it is equal to 0, the bit 1 of parameter 8671 is set to 1	uint8
8671	Status of timers: bit 0→timer1, bit 1→timer2 or status of last operation: bit 2→negative result, bit 3→zero result	int16
8672	Force a double word operation: When the unit is powered on, this is 0. If it is set to 1, the first mathematical operation executed by the uPLC is done by using three double word type operands. After the execution of the operation 8672 is automatically set to 0. The double word result of the mathematical operation is plitted into two adiacent register of 16bits. If the result parameter PC is set to 8683, the double word result is splitted into 16bit registers⇒ 8683 (LSB) and 8684 (MSB)	int16
4620	Status of digital inputs	int16
4621	Status of digital outputs	int16
4622	Motion controller table index	int16
4623	Set motion controller table index (the uPLC logic will reset this value after receive 4623 = 1)	int16
4624	Used in combination with SET function, when set to 1, the SET function becomes TOGGLE funciton (this means if bit is set will be reset, if the bit is reset will be set).	int16
