GC_USER_GCODE (175)

ID 175

Application:

PLC

Group: MOTION

Short description:

Function that executes the user's G-code.

Inputs:

no.	type	impulse	mark	notes
1	B	yes ( 0->1 )	exe	Block activation

Outputs:

no.	type	impulse	mark	notes
1	B	yes ( 0->1->0 )	Out1	Digital output no. 1
2	B	yes ( 0->1->0 )	Out2	Digital output no. 2
3	B	yes ( 0->1->0 )	Out3	Digital output no. 3
4	B	yes ( 0->1->0 )	Out4	Digital output no. 4
5	B	yes ( 0->1->0 )	Error	Error - G-code was not defined by this function block

Settings:

no.	type	mark	notes
1	I	Code_1	G (=1) or M (=2) - code activating output Out1
2	I	Value_1	Value activating output Out1
3	I	Code _2	G (=1) or M (=2) - code activating output Out2
4	I	Value_2	Value activating output Out2
5	I	Code _3	G (=1) or M (=2) - code activating output Out3
6	I	Value_3	Value activating output Out3
7	I	Code _4	G (=1) or M (=2) - code activating output Out4
8	I	Value_4	Value activating output Out4

Function operation:

After changing the exe signal from 0 to 1, the function checks the value of the M or G code written in the special registers R3071 or R3077 with the values defined in the block settings. If there is a value of 1 in the special register R3091 (the last code was the G code), then the R3071 register is checked, and if the value of 2 in the R3091 register (the last code was the M code), then the R3077 register is checked. When the values in the registers are consistent with the values from the block settings (R3091 = 1 & Code_n = 1 & Value_n = R3071 or R3091 = 2 & Code_n = 2 & Value_n = R3077, where n = 1 ... 4) then a corresponding digital output Out1 to Out4 is activated for one program cycle. If the G-code does not correspond to any defined for this block, then a high signal will appear on the 'Error' output for one controller cycle.
