Schneider Electric LUFP9 user manual Services of instance 16#01 of class 16#AA

10. Appendix D: DeviceNet Objects

ID	Access	Name	Need	Type	Value
16#11	Get	IN total length	Optional	UINT	16#0020

This attribute indicates the total size of the input data used in the gateway’s extended memory (IN bytes supported), expressed as a number of bytes. This size is equal to the value of the previous attribute (size of inputs in DPRAM), as it only contains input data. The values of attributes 16#0F, 16#10 and 16#11 are all identical. With the LUFP9 gateway’s default configuration, the value of this attribute is equal to 32 bytes.

N.B. The gateway’s extended internal memory is different from the DPRAM memory, dealt with in the rest of this guide. As a result, when using the gateway, you will not have to worry about it.

16#12

Get OUT cyclic I/O length Optional UINT 16#0020

This attribute indicates the total size of the cyclic output data (I/O OUT data), expressed as a number of bytes. This size covers all the gateway’s memory space occupied by Modbus output data, free locations also being counted. With the LUFP9 gateway’s default configuration, the value of this attribute corresponds to the size of the output area of the gateway, that is to say 32 bytes.

16#13

Get OUT DPRAM length Optional UINT 16#0020

This attribute indicates the total size of the output data and parameters in the gateway’s memory (valid OUT bytes in DPRAM), expressed as a number of bytes. This size covers all of the gateway’s memory space occupied by Modbus output data and parameters, free locations also being counted. Since no output parameters are defined, the values of attributes 16#12 and 16#13 are both identical. With the LUFP9 gateway’s default configuration, the value of this attribute is equal to 32 bytes.

16#14

Get OUT total length Optional UINT 16#0020

This attribute indicates the total size of the output data used in the gateway’s extended memory (OUT bytes supported), expressed as a number of bytes. This size is equal to the value of the previous attribute (size of outputs in DPRAM), as it only contains output data. The values of attributes 16#12, 16#13 and 16#14 are all identical. With the LUFP9 gateway’s default configuration, the value of this attribute is equal to 32 bytes.

N.B. The gateway’s extended internal memory is different from the DPRAM memory, dealt with in the rest of this guide. As a result, when using the gateway, you will not have to worry about it.

16#15	Get	Reserved attribute	Optional	UINT	16#0000
	This attribute is not used.
16#16	Get	Application indication	Optional	USINT	(8-bit register)

This 8-bit register is reserved for the gateway’s applicative card, that is to say the card on which the AnyBus-S DeviceNet card is inserted. The various bits of this register are primarily used when internal commands of the gateway are intended to act on the gateway’s memory. These bits are not intended to be used by the DeviceNet master and will not be described here.

16#17

Get AnyBus indication Optional USINT (8-bit register)

This 8-bit register is reserved for the gateway’s AnyBus-S DeviceNet card. The various bits of this register are primarily used when internal commands of the gateway are intended to act on the gateway’s memory. These bits are not intended to be used by the DeviceNet master and will not be described here, except for bit 4:

Bit 4: This bit is set to one once the gateway’s AnyBus-S DeviceNet card has been initialized.
