Product Information	February, 1999
BRIDGE CS-L2

3.1 Removed Errors (already with V02.00)

•F: Time synchronization

A:Time telegrams were not always transmitted at high priority. In exceptional circumstances several time telegrams with different time data were transmitted

shortly after one another.

M:The throughput-time of time telegrams in the bridge was optimized.

•F: Behavior when switch set to STOP

A:In the STOP state, old telegrams were kept (e.g. several time telegrams at the same time) and full receive buffers on the bridge's bus couplings caused the other

bus participants to repeatedly send messages unnecessarily.

M:Telegrams are no longer kept in the STOP state.

•F: Behavior when switch set to MRES (Soft-Reset)

A:This function caused the bridge to stop, which could then only be restarted with a cold start.

M:Functions according to Table 4-1 of the technical description.

•F: Loss of telegrams during periods of high activity

A:Telegrams can be lost during periods of high activity when the target address cannot accept the telegrams from the bridge quickly enough.

M:The reception part of the bridge is choked during periods of high activity. In this way, the transmitter learns of the bridge’s coupling backlog and can, if necessary, repeat the telegrams. This means that telegrams are no longer lost in this situation.

•F: Control of STOP LED when bus coupling errors occur

A:If the bridge recognizes a bus coupling error, it is reinitialized. This is indicated by addressing the STOP LED, even if the bridge functions correctly afterwards.

M:If a bus coupling is successfully reinitialized due to an error, this event is signaled by a flashing LED, either LED USR1 (for TPM478) or USR2 (for CP5412). This condition is then terminated if the key switch is set to any other position.

•F: Behavior when switch set to RUN-P

A:No function was allocated to this setting in the technical description (Tab. 4-1). It is, however, identical with the RUN setting.

M:Adaptation of the technical description

•F: Startup still occurs if configuration file is missing or configuration parameters are incorrect

A:If certain configuration parameters are incorrect or the configuration file

BR_SYS.INI is missing, the bridge is started with the bus parameters BA=3 and

TA=20 without taking the existing network configuration into consideration.

M:The RUN LED flashes and the INTF LED (according to Table 4-1 of the technical description) is continuously illuminated to indicate that the configuration parameters are incorrect or missing.
