Program Parameters Instruction

† Fixed when service set to “Set_Attribute_Single” .

Note:

This command writes parameter values to RAM and will be lost once power is cycled to the RM-89 . If you wish to use these

parameters after cycling power, you must issue a Save To Flash Instruction as described on page 36 .

Program Parameters Data Format

Twelve bytes of data must be written to the RM-89 as part of this instruction . Table 5 .2 lists the format of the data words . The

location of these words must be entered into the message instruction . For RSLogix 5000 programs, this location is called

“Source Element” . For RSLogix 500 programs, this location is called “Send Address” .

Byte

Word

Parameter

Description

Direction Count-

ing Toggle

“0” = Clockwise increasing counts looking at shaft .

“1” = Counter-Clockwise increasing counts looking at shaft .

Scaling Function

Control

“0” = Disable Scaling Function . The full resolution of 65,536 counts

per turn is used for the Measuring Units per Span .

“1” = Enable Scaling Function . The number of counts per turn is set

by the Measuring Units of Span parameter below .

Counts per Turn

Sets the number of counts generated over a single turn if

the Scaling Function Control parameter equals “1” . Always

sets the number of pulses per turn reported in velocity

data . This value ranges from 1 to 65,536 . A value of

39,370 (16#99CA) is shown to the right .

Total Measure-

ment Range

Sets the number of counts before returning to zero . This

value is used regardless of the state of the Scaling Func-

tion Control parameter . Parameter ranges:

•

Single Turn RM-89:

Range of 0, 2 to 65,536

•

Multi-turn RM-89:

Range of 0, 2 to

268,435,456

A value of 648,000 (16#0009 E340) is shown to the right .

Velocity Format

Format of the velocity data . Byte 11 must always equal

“1F” . Byte 10 = “04” for pulses/second, “05” for pulses/mil-

lisecond, “07” for pulses/minute or “0F” for revolutions/

minute . A value of “1F04” to the right would set the unit

of measure to pulses/second .
