Progress or State Value
Operation pending (this node has not started yet) -1
Percentage download complete (downloads only) 1-100
Download or reset successful 0
CRC failure at drive (downloads only) -5
Flash save failure at drive (downloads only) -6
Failure with TCP connection to drive -8
Table 77 P37636 (OS download or reset progress or status control parameter for EPLD0)
The EPL operation error code (P37637) values are the same as P37386. The
attached axis number (P37638) is -1 if no axis is attached, otherwise it is the
axis number (0-15). Node status (P37639) is updated each time the network
is started, stopped, or a node is lost.
If for any reason a controlled node stops being operational, the controller will
automatically try to restart it. The Node Failure Count (P37641) indicates the
number of times this has happened since the overall network became
operational. The Operational Duration in Seconds (P37640) indicates how
long this node has been operating, either from the start time of the original
network operation, or since being restarted by the controller.
Table 78 and Table 79 give all the digital I/O definitions and where they
appear for EPLD0 through EPLD3 in the ACR9030 and ACR9040. For the
next group of 4 EPLDs, add 32 to the bit number, and 1 to the flag parameter
number. For example, the digital inputs for EPLD4 are contained in P4201,
starting with bit 3360. (The second column of the tables contains information
useful for understanding how to use the ACR9030 and ACR9040 with an
EPL drive other than the Aries EPL. In that case, consult that drive’s user
guide to know how to interpret those bits.)
