Reporting of duplicate IP address The PACSystems RX7i does not log an exception or a fault in the 

Controller Fault Table when it detects a duplicate IP address on the 

network. 

Multiple zero period EGD exchanges 

may not produce similar numbers of 

samples

If more than one EGD produced exchange is configured for a production 

period of zero, the exchanges may not produce similar numbers of 

samples. Due to the way that scheduling occurs when multiple exchanges 

are scheduled “as fast as possible,” some zero period exchanges may 

produce significantly more samples than others. For more consistent EGD 

production, configure the produced EGD exchanges with non-zero 

production periods.

Changing IP address while SRTP 

connection open may generate log 

events

Open SRTP Server connections established with a remote SRTP client 

are not terminated as expected when the RX7i’s IP address is changed 

(typically by storing a new HW Configuration to the RX7i). A Series 90 

SRTP client (“SRTP channels”) reports either a 9690H or 0190H status; 

the SRTP connection may remain open until the connection is terminated 

as a result of a client timeout. 

Series 90-70 datagrams are not 

supported

Series 90-70 datagrams are not supported. This means that Series 90-70 

- format variable list requests from Host Comm Toolkit applications will 

fail. (Series 90-30 – format datagrams are supported, but cannot access 

%P or %L memory in the RX7i.) 

AUP parameter should not be changed The Advanced User Parameter “wsnd_buf” should not be changed by the 

user. Changing the value of this parameter may cause the LAN LED to go 

out and the Ethernet Interface to drop connection.

Heavy load can block station manager As explained in TCP/IP Communications for PACSystems Station 

Manager Manual, GFK-2225, Chapter 1, a heavy EGD and/or SRTP load 

can block Station Manager operation. 

One-time delay of EGD Production (and 

possibly Consumption) if more than 24 

SRTP Server Connections are started 

simultaneously

If more than 24 SRTP Server connections are established simultaneously, 

EGD Production may be briefly delayed for each connection after the 24th

when the connections are first made after power is applied. If EGD 

consume acceleration has been disabled, then EGD Consumption will 

also be delayed. The delay only occurs once when the SRTP Server 

connection is established for the first time after Powerup. No delay is 

experienced for the first 24 SRTP Server connections.

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.
