● TIM modules with an RMOS version as of 2.08 are routing-compliant but involve
restrictions regarding the number of remote subnets. No more than 20 remote subnets
may be configured in the SINAUT project.
● TIM modules with an RMOS version as of 2.14 are fully routing-compliant.
The operating system of the TIM modules can be upgraded to the current version. A special
cable is required for this. This can be borrowed from the hotline. Along with the cable, the
current version of the operating system is supplied on diskette with instructions on upgrading
using a PG/PC.
4.2.4 TIM firmware for TIM 4
Not only the version of the operating system but also the version of the TIM firmware for the
TIM 4 decides whether a TIM is suitable for PG routing. In this respect, there are versions
ideally suited for PG routing and earlier versions that mean certain restrictions.
For PG routing, a TIM firmware version of V 3.46 is generally recommended. It depends on
the driver activated on the TIM (dedicated line or dial-up network driver) whether an older
version will be adequate. PG routing over the dedicated line driver is possible as of firmware
version V 3.14. If the dial-up network driver is activated on a TIM module, firmware version V
3.46 or higher must be installed.
4.2.5 Settings for SINAUT networks
Retry factor and maximum message length
PG routing can only be used when the maximum message length network parameter for the
SINAUT networks is set to a maximum of 240. Since this value is normally entered as default
in the
Properties dialog for SINAUT networks, this is normally already set.
If a transmission speed of 1200 bauds is set in a SINAUT network, make sure that the retry
factor is higher than 0. We recommend that you use the default values available for the retry
factor in the configuration dialogs:
● For dedicated lines: 3
● For dial-up networks: 7
4.2.6 Recompiling system blocks
If you want to enable PG routing in an existing SINAUT ST7 system, the project must be
recompiled in the subscriber management of the SINAUT configuration tool (as of V 3.0). It is
adequate to simply recompile the new SDBs there. The programs for CPU modules do not
change for PG routing.
After compiling the SDBs, the entire SINAUT system configuration must be downloaded and
activated on the TIM modules.
