EPL Drive Information Parameters and I/O Flags 
Table 75 gives all the user-set control parameters for EPLD0. For higher 
numbered ETHERNET Powerlink drives (EPLD), work from EPLD0 and add 
n x 16 to each parameter number. For example, for EPLD1 Node ID, add 1 x 
16
 to the parameter number for EPLD0 Node ID (P37632) to get P37648. 
The control parameters must be set by the user before the network is started. 
Save the parameters denoted with an asterisk (*) with the 
ESAVE command. 
Control Parameters for EPLD0  P Number 
Node ID *  P37632 
Reserved  P37633 
Drive mode *  P37634 
TCP/IP Port number *  P37635 
* Saved with the ESAVE command 
Table 75 Control Parameters for EPLD0 
 
The “Drive Mode” parameter is derived from the DSP-402 specification, and 
takes a value of 7 for Interpolated Position Mode, the only supported mode. It 
is included as a parameter to accommodate a possible future expansion in 
supported modes. The TCP/IP Port number (P37635) is required for TCP/IP 
connection to a drive, discussed in the section “Basic Ethernet Connections” 
on page 179. 
Table 76 gives all the status parameters for EPLD0. The controller 
automatically updates the status parameters, and the user should not modify 
them. 
Status Parameters for EPLD0  P Number 
OS download or reset progress or status  P37636 
EPL Operation Error Code (0 means no error)  P37637 
Attached Axis Number (Established by the ATTACH AXIS 
command) 
P37638 
Node Status (0=never found, 1=found, 2=found then lost)  P37639 
Operational Duration in Seconds  P37640 
Node Failure Count  P37641 
Reserved  P37642-P37647 
Table 76 Status Parameters for EPLD0 
 
P37636 indicates the current progress, or final status of an OS download or 
reset initiated by ACR-View. The potential values and their meanings are 
listed in Table 77 in the order that would occur during the process. The status 
values persist after the operation is complete.
