Field Description Read/Write Description
Start Network R/W Set the bit to start the EPL network. The Managing Node (MN) places the Controlled Nodes (CN) into a pre-operational state, configures the CNs, then places the CNs into an operational state. The bit is self-clearing.
Reset Network R/W Set the bit to reset the EPL network to a non-operational state. The bit is self-clearing.
SDO Send Request R/W Setting the bit sends SDO data specified in P37378-37381. The bit is self-clearing.
SDO Read Request R/W Setting the bit reads SDO data specified in P37378-37381. The bit is self-clearing.
EPL Controller Installed R EPL controller card has been detected.
Network Operational R The EPL controller is exchanging data with the drives.
Network Start Failed R An attempt to start the network using bit 16640 has failed. To determine why the attempt failed, look at P37384-P37386.
EPL Node Failure R An individual EPL node has failed. To determine which node failed, look at P37385
EPLD Stream Open R An EPLD stream is open (using the OPEN command). To determine which EPL drive is communicating, and its device number, look at P37387 and P37388
EPLD Stream Disconnected R Set when an unexpected disconnection with an EPL drive occurs. The controller automatically closes the EPL communication stream.
The bit remains set until the user clears it, or another OPEN EPLD command is sent to the same drive to reestablish communication.
EPL Drive(s) Enabled R The controller will not allow the network to be started or reset if any of the EPL drives are enabled.
Insufficient Period R Set when the period is too low. Network will not start.
Starting Network R Indicates that a network start is underway.
Resetting Network R Indicates that a network reset is underway.
Writing SDO Data R Indicates that a SDO write is in process.
Reading SDO Data R Indicates that a SDO read is in process.
Opening EPLD Stream R Indicates that the process of opening an EPLD stream is underway.
