Possible settings: 12
T3: Reply timeout 12
When a primary message is sent to the host computer, the station waits for up to the number of
seconds specified for T3 for the secondary message from the host computer.
Range of values: 1 - 120 seconds 12
T5: Connect separation timeout 12
This parameter determines the waiting time between successive attempts to establish a connec-
tion. This is only important if the station has been configured as the ACTIVE ENTITY.
Range of values: 1 - 240 seconds 12
T6: Control transaction timeout 12
After sending the message "Connect.req" or "Linktest.req" to the host computer, the station waits
for up to the number of seconds specified for T6 for the "Connect.rsp" or "Linktest.rsp" message.
The TCP/IP link is then interrupted.
Range of values: 1 - 240 seconds 12
T7: NOT SELECTED timeout 12
Once the TCP/IP connection has been established, the station configured as the PASSIVE EN-
TITY waits for up to the number of seconds specified for T7 for the "Select.req" message from the
host computer. The TCP/IP link is then interrupted. A successful exchange of "Select.req" and
"Select.rsp" forms the basis for the conversion of the TCP/IP connection into an HSMS connection.
Range of values: 1 - 240 seconds 12
T8: Network intercharacter timeout 12
Reception of an individual HSMS message must take no longer than the number of seconds spec-
ified for T8. Otherwise the TCP/IP link will be interrupted.
Range of values: 1 - 120 seconds 12
CE: Connection Establishment Timeout 12
After sending a TCP/IP connect command, a station which has been configured as an ACTIVE
ENTITY waits for up to the number of seconds specified for CE for a connection to be established
successfully or for a status message. After this time, it is assumed that the command was not re-
ceived correctly. 12

CA: Circuit Assurance 12
This parameter determines the waiting time between sending successive "Linktest.req" mes-
sages. These messages check that the HSMS connection is working correctly. If the value 0 has
been entered for CA, no "Linktest.req" messages are sent. 12
TG: Grace period 12
While a SECS-II connection is being established, the SDR component of the GEM interface buff-
ers all the messages to be sent to the host computer. If the SECS-II connection cannot be estab-
lished within the number of seconds specified for TG, these buffered messages will be sent to the
host computer. Otherwise they are rejected by the SDR component and have the status F_DELV.12
MS: Memory Stall 12
The SDR component of the GEM interface tolerates the status that all internal buffers are full and
that the host is attempting to send further data packets for up to the number of seconds specified
for MS. The TCP/IP connection is then ended to prevent the network becoming overloaded. 12
WS: Write Stall 12
The SDR component of the GEM interface tolerates the status that data packets to be sent are
not received by the TCP/IP connection for up to the number of seconds specified for WS seconds.
The TCP/IP connection is then ended. 12

12.2.2.4 GEM Connection Statuses
The status window of the user interface keeps the operator informed of the status of the connec-
tion to the host computer. The various statuses are indicated by the changing background color
of the GEM icon. 12
12
Status of the Host Computer Connection 12
(GEM icon red, yellow or green) 12
Meaning of the colors:
– Red No connection
– Yellow Setting up connection
– Green Connection established
12
In addition to displaying the status of the host computer connection, the status window also shows
whether messages have been received from the host computer. The current status is indicated by
the changing background color of the envelope part of the GEM icon. 12
Statuses: 12
no messages present 12
(envelope icon light) 12
