416NHM30030 PLC module

In rare instances, after power cycle, the Ethernet Interface may log the following fault, Event = 28H, Entry 2 = 000eH. This fault can be safely ignored. Release 2.00 PLC Faults are not Identified on Web Page When any PLC Fault Table entries defined for Release 2.00 are displayed using the Ethernet interface web server, the PLC Fault description contains only a generic message instead of the proper fault text.EGD Commands return COMMREQ Status 8F90H (= invalid IP address) when addressed to initiating Ethernet Interface’s own IP address. If you wish to send an EGD command to yourself, please use the loopback IP address (127.0.0.1). Unexpected EGD COMMREQ Status EGD Commands may return COMMREQ Status 9590H (= internal error) instead of the expected B190H (= Can’t locate remote node) when unable to locate a remote device on the network.

Too many EGD Commands Reported as Internal Error

 The Ethernet Interface supports 10 simultaneous EGD commands. When an 11th EGD Command COMMREQ is issued, the CSW value 9590H (= internal error) is returned. EGD Command Passwords are not Supported Optional passwords are not allowed within EGD Command COMMREQs. Very Heavy EGD Production/Consumption at Server May Cause EGD Command Timeouts Very heavy EGD production and/or consumption at a server device may cause EGD command timeout errors when another device attempts to send EGD commands to that server. If EGD commands must preempt normal production, you may set the “gcmd_pri” Advanced User Parameter to 2 (see GFK-2224, Appendix A). Note that by doing so, EGD exchange production may be delayed. SRTP Server Errors Can Cause Timeouts at Channels Client The SRTP Server in the PACSystems Ethernet Interface can encounter various errors when the remote Series 90 PLC client takes down an SRTP connection and then establishes a new connection. This can cause unexpected channel timeout errors 0190H or 0290H at the client. The SRTP server errors in the Ethernet exception log are identified as Event = 2; Entry 2 may be 001cH, or 0021H.

Usage of New IP/Subnet Mask Configuration

 Because the Ethernet interface operates using a retained set of IP address + subnet mask information, a change to these values does not take effect until a restart of the module or power cycle of the rack containing the module. The user should be aware when altering these configuration values that their effect is not immediate. Cannot Change EGD Class 2 UDP Port Number Processing an Advanced User Parameter File containing parameter “gctl_port” does not actually change the value. COMMREQ Length Error The COMMREQ Status Word value 8190H (="COMMREQ is too short") may also be reported for EGD Command COMMREQs that are too long (contain more words than expected). No CPU fault logged when Ethernet Interface in fatal blink code The CPU does not log any PLC or I/O Faults when the Ethernet Interface has a fatal blink code. The user’s ap
