ACR9030 and ACR9040 EPL Commands,
Parameters and Flags
A new user command related to EPL is the
ATTACH AXIS ELPD
command,
which will be described later in this appendix. The EPL network configuration
requires the user to set some of the parameters, and the rest of the
configuration is automatically done by the ACR9030 and ACR9040. The
ACR9030 and ACR9040 report the status of the EPL network and nodes in
parameters and flags.
NOTE:
ACR-View utilizes a wizard-based configuration tool to set all
required parameters.
EPL Network and Node Control Parameters
The tables below list the network and drive parameters the user must set,
and their default values. (The default values are applied on power up if user-
supplied values have not been saved with the ESAVE command.)
The parameter for the EPL network must be set for any network operation:
EPL Network Parameter P Number Default Value
Number of controlled nodes (CN) P37376 1 (valid range 0-15)
Table 69 User-Set Network Parameter
The parameter for the EPL drives must be set for each EPL drive implied by
P37376. The following shows the parameter for EPLD0, where “Node ID”
refers to the external device setting, established by a switch on the device:
EPLD0 Parameter P Number Default Value
Node ID P37632 1 (valid range 1-99)
Table 70 User-Set Node Parameter
The entire list of network and node control and status parameters is given
later in this appendix.
Starting, Configuring and Resetting the Network
NOTE:
The following procedure is stated for reference only. If using ACR-
View, the configuration wizard automatically accomplishes this procedure for
you.
The user may command the ACR9030 or ACR9040 (MN) to start or reset the
network at any time using the
EPLC ON
and
EPLC OFF
commands,
respectively, or by setting control bits in the EPL Network Control/Status flag
parameter (P4616). The
EPLC ON
and
EPLC OFF
commands work by
internally setting the control bits discussed below.
When the network is started via
EPLC ON
or bit 16640, the ACR9030 or
ACR9040 initially places all controlled nodes (CN) into the “pre-operational”
state. During this state, the MN interrogates and configures the CNs as
required. The CNs are then placed into the “operational” state, and the
automatic data transfer between the CNs and the MN takes place.
