3-3 Explicit Messaging

3-27

Communicating with the GT2 series

- DeviceNet Compatible Network Unit DL-DN1 User’s Manual (GT2) -

The following tables list the command parameters used in explicit messaging to read/

write the settings and status of sensor amplifiers and to issue motion commands.

For details about how the master unit performs explicit messaging using command

parameters, see:

"Issuing a Motion Command to a Sensor Amplifier" (page 3-23)

"Reading/Writing Settings or Status of a Se

nsor Am

plifier" (page 3-24)

Common Command Parameter List

The table below describes command parameters which are common to the DL-DN1.

InstID: Instance ID; AttrID: Attribute ID

Attribute R: Read; R/W: Read/Write

64 Status

Bit 0 - 12: Unused

Bit 13: Sensor ready

Bit 14: Warning state

RWORD0*1

65 Error state

The error state values of sensor amplifiers

(ID 01 to ID 15) are output as they are

assigned to bits 0 - 14.

RWORD0

0: No Error

1: Error

66 Warning state

Not used with the GT2 series.

RWORD0−

67 System reserved

Current value

property

This property is output by assigning sensor

amplifiers (ID 01 to ID 15) bits 0 - 14.

The output occurs when the measured

value is non-numeric: "over," "under," or

"invalid."

RWORD0

0: Normally mea-

sured value

1: "over," "under," or

"invalid"

69 to 6B System reserved

6C Error ID number

Error details.

If there are errors with multiple ID numbers,

the error information for the smallest ID

number is output.

RUINT0

6D Error code R UINT 0

Warning ID

number

Not used with the GT2 series.

6F Warning code R UINT 0

70 to 73 System reserved

74 HIGH

The HIGH state is output by assigning sen-

sor amplifiers (ID 01 to ID 15) bits 0 - 14.

RWORD0

0: OFF

1: ON

75 LOW

The Low state is output by assigning sen-

sor amplifiers (ID 01 to ID 15) bits 0 - 14.

RWORD0

0: OFF

1: ON

76 GO

The GO state is output by assigning sensor

amplifiers (ID 01 to ID 15) bits 0 - 14.

RWORD0

0: OFF

1: ON

77 HH

The HH state is output by assigning sensor

amplifiers (ID 01 to ID 15) bits 0 - 14.

RWORD0

0: OFF

1: ON

78 LL

The LL state is output by assigning sensor

amplifiers (ID 01 to ID 15) bits 0 - 14.

RWORD0

0: OFF

1: ON

79 to 8C System reserved

Comparator

value "invalid"

If the

comparator

values for sensor amplifi-

ers (ID 01 to ID 15) are invalid

(-----), they are output by assigning them to

bits 0 - 14.

RWORD0

0: Normal value

1: Invalid
