Table 1-8 Slave Parameters
Item Description
IDENT NO. DP-Slave identification number.
This parameter specifies the identification number of a DP-Slave to be connected.
SLAVE FLAG Slave specification bit flag.
Bit 7: Active
0: Does not perform communication with the DP-Slave.
1: Performs communication with the DP-Slave.
Bit 6: New_Prm
0: Does not send new parameter data to the DP-Slave.
1: Sends new parameter data to the DP-Slave.
Bits 5 to 0: Reserved (to be service to 0)
SLAVE TYPE Manufacturer-specified type indication for the DP-Slave.
LOCK REQ, UNLOCK
REQ
When LOCK_REQ=ON and UNLOCK_REQ=OFF are set, the DP-Slave disables the
DP-Master from modifying the parameters.
When LOCK_REQ=OFF and UNLOCK_REQ=ON are set, the DP-Slave allows the
DP-Master to modify the parameters.
SYNC REQ When ON is set, the Sync control command can be used.
FREEZE REQ When ON is set, the Freeze control command can be used.
WD REQ When On is set, disconnection detection is performed.
WD FACT1, WD
FACT2
Coefficients for disconnection detection time determination.
10 × WD_FACT1 × WD_FACT2 (msec)
MIN TSDR Minimum wait time until a response is returned to the DP-Master. (Unit: Bit time)
GROUP IDENT This parameter specifies groups for the DDLM_Global_Control instruction. Each bit
represents a group. Up to eight groups can be specified.
USER PRM DATA User parameter data.
Data necessary for the slave parameters and specified by the manufacturer.
CONFIG DATA Configuration data.
Data for specifying information such as the size of I/O data to be exchanged between the
DP-Master and DP-Slave.
SLAVE USER DATA Slave user data.
Data specified by the manufacturer to indicate the characteristics of the DP-Slave.
