7. 4. Communication scanner

On the graphic display terminal, in the [1.2 - MONITORING] (SUP-)menu ([COMMUNICATION MAP] (CMM-)submenu):

-The [COM. SCANNER INPUT MAP] (ISA-)submenu is used to display the value of the 8 communication scanner input variables [Com Scan Inp val.] (NMp).

-The [COM SCAN OUTPUT MAP] (OSA-)submenu is used to display the value of the 8 communication scanner output variables [Com Scan Outp val.] (NCp).

Input variable	Scanner parameter
No. 1	[Com Scan In1 val.] (NM1)
No. 2	[Com Scan In2 val.] (NM2)
No. 3	[Com Scan In3 val.] (NM3)
No. 4	[Com Scan In4 val.] (NM4)
No. 5	[Com Scan In5 val.] (NM5)
No. 6	[Com Scan In6 val.] (NM6)
No. 7	[Com Scan In7 val.] (NM7)
No. 8	[Com Scan In8 val.] (NM8)

Output variable	Scanner parameter
No. 1	[Com Scan Out1 val.] (NC1)
No. 2	[Com Scan Out2 val.] (NC2)
No. 3	[Com Scan Out3 val.] (NC3)
No. 4	[Com Scan Out4 val.] (NC4)
No. 5	[Com Scan Out5 val.] (NC5)
No. 6	[Com Scan Out6 val.] (NC6)
No. 7	[Com Scan Out7 val.] (NC7)
No. 8	[Com Scan Out8 val.] (NC8)

Configuration of these variables is described in the "Configuration" section.

Example of communication scanner display on the graphic display terminal:

RUN			NET		+50.00Hz		80A

		COM. SCANNER INPUT MAP

Com Scan In1 val.				:			34359
Com Scan In2 val.				:			600
Com Scan In3 val.				:			0
Com Scan In4 val.				:			0
Com Scan In5 val.				:			0

	Code					Quick

Com Scan In6 val.				:			0
Com Scan In7 val.				:			0
Com Scan In8 val.				:			0

RUN			NET		+50.00Hz		80A

		COM SCAN OUTPUT MAP

Com Scan Out1 val.				:			15
Com Scan Out2 val.				:			598
Com Scan Out3 val.				:			0
Com Scan Out4 val.				:			0
Com Scan Out5 val.				:			0

	Code					Quick

Com Scan Out6 val.				:			0
Com Scan Out7 val.				:			0
Com Scan Out8 val.				:			0

In this example, only the first two variables have been configured (default assignment).

[Com Scan In1 val.]	= [34343]	Status word = 34359 = 16#8637	V	Drivecom "Operation enabled" state,
				reverse operation, speed reached
[Com Scan In2 val.]	= [600]	Output speed = 600	V	600 rpm
[Com Scan Out1 val.]	= [15]	Control word = 15 = 16#000F	V	"Enable operation" (Run) command
[Com Scan Out2 val.]	= [598]	Speed reference = 600	V	598 rpm
