• this function block is used to synchronize and distribute the system
time throughout the subrack and to set the system time. In this case,
system time means the date and time of day.
The system time is distributed via CP52A0.
• the RTCM function block can only be configured in a sampling interval
128 ms <= TA <= 512 ms.
• the RTCM function block may only be configured once for each
subrack, and then only on the CPU which is located the furthest to the
left in the subrack.
The RTCM function block searches in the initialization mode, using the
TM input, for the module on which the system time source (master
system time) is controlled for the complete subrack. The master system
time can come from its "own" CPU, a CP51M1/CP5100 or a CP52A0.
The function block then searches all CS12/13/14 modules to distribute
the system time to the other subracks.
After all of the initialization tasks have been completed, the function block
updates the system time cyclically every 10 seconds on the
communications buffer (for system time synchronization on the particular
subrack) and on all CP52A0 modules.
Within any subrack, the system time is automatically synchronized
between the CPUs.
If the configured name of its own CPU is specified at input TM, then it
defines the system time itself. In this case, the block inputs XYR, XMO,
XDA, XHR and XMI are read-in when the signal at input IS changes from
0 to 1, and transferred as system time. As long as the IS block input is
not set, then the system time starts to run with the time buffered by the
battery or from the pre-setting 1.1.1993 00:00.

If illegal values are present at the block inputs to set month, day, hour
and minute, an entry is made in the communications error field and the
function block becomes inactive (further, the error number is output at
YTS).
If a module name is specified at the TM connection which is different than
that configured, then the block inputs XYR, XMO, XDA, XHR, XMI and IS
are only evaluated if the configured source has failed..
Block output TS indicates whether the system time was only received in
the current processing cycle (TS = 0) or was self-controlled (TS = 1).
Normally, the system time is received from the module, whose configured
name was specified at input TM. If the system time is no longer
generated there, then the RTCM automatically switches-over to its own
system time and uses this as master system time. This changeover is
flagged at output TS.
If a deviation of more than 100 ms is identified between the master
system time and its own time, between two synchronizing intervals, then
the RTCM evaluates the deviation as system time adjustment (e.g. when
changing-over from summer- to winter time).
Block output TUC indicates how many system time adjustments the
function block has already identified.
TM Initialization input for the configured coupling module name which should be
used for the master system time.
XYR Year, permissible entry: XYR = 00 to XYR = 99. The block input is only read when IS
changes from 0 to 1 and if the configured name of its own CPU module is specified at
TM.

corresponding to block inputs XYR, XMO, XDA, XHR and XMI, and if required, block
output TUC is incremented (for deviations greater than 100 ms). The IS input is only
processed, if its own module name was configured at input TM.

received from the module configured at input TM (TS = 0) or is self-controlled
(TS = 1), e.g. if the master system time fails.
(default : 0)
TUC System time version counter. If a deviation of more than 100 ms is identified
between the master system time and its own time, between two synchronizing intervals,
then the RTCM evaluates the deviation as system time adjustment. The TUC block
output is incremented at each system time adjustment.

The SNTPR block receives a TCP-IP time telegram according to
RFC 2030, and converts the time into the internal TDC format. If the
CP51M1/CP5100, configured at the CT1, is also configured as a time
source at the RTCM, then the function block assumes the
synchronization function. The second CP51M1/CP5100 (configured at
CT2) can then be used as redundant time source. Only a time sender
SICLOCK can be used as a time source.
The time of the 'Master Clock' is received via the first CP51M1/CP5100
and the time of the 'Standby Clock' via the second CP51M1/CP5100. If
the telegrams from the 'Master Clock' fail, then after the time, set at input
TIO, the telegram of the 'Standby Clock' is used for synchronization. A
changeover is made to the internal clock if this is not configured or has
failed.
Once a fault has been removed, then the time from the source is
automatically evaluated with the highest priority (master before slave
before internal clock).

buffer coupling. The communications buffer coupling can be set-up on
all communications buffer modules.
• the function block may only be configured once for each subrack, as
there is only one communications buffer module for each subrack.
Multiple configuring is identified during initialization and results in an
entry in the communications error field.
• the function block may only be configured in the sampling interval
32 ms <= TA <= 256 ms. Otherwise, an entry is made in the
communications error field.
While the function block is being initialized, general preparations are
made to enable the coupling. The coupling is only enabled after the
normal mode has been executed several times.
After the coupling has been enabled, the central block monitors that
transmitters and receivers are correctly logged-on. Further, if required, it
re-organizes and updates the block output CDM at each processing
cycle.
The complete data interface is re-formatted by setting the CDV input.
This option should be used, if
• an application (e.g. the message evaluation function block MSI)
flags that it cannot log-on any additional channel at the data interface, as
there is no sufficient memory space available.
If the CDV block input is set again, this is only taken into account if the
CDV input was reset (i.e. was at 0) for at least 2 sampling times after re-
organization was completed. Otherwise the data at the input is ignored.
The CDM block output provides information about the coupling status.
The output is 1, if the coupling is enabled for general transmit/receive
operation. The CDM block output is 0, as long as the coupling is being
initialized or is being re-initialized (after a temporary fault), or the memory
is being re-formatted (refer to CDV connection).
The computation time information in the technical data refers to a typical
task processing. During re-organization, the computation time is
extended over several processing cycles up to 370 µs.

(CP52A0 module).
• the function block may only be configured in the sampling interval
32 ms <= TA <= 256 ms. Otherwise, an entry is made in the

Mode of operation
While the function block is being initialized, general preparations are
made to enable the coupling on CP52A0 side. The coupling is only
enabled after the normal mode has been executed several times.
After the coupling has been enabled, the central block checks that
• the CP52M0 side is still present
• the coupling from the CP52M0 side is enabled.
Further the central block monitors:
• the number of active subracks (CP52A0)
• the status of the registrated coupling partners on CP52A0 side
Transmitters and receivers in the slave-side subrack can only access the
GDM memory at the data interface after the @SRACK central block has
enabled the coupling.

This function block converts an analog voltage into a digital value with
voltage/frequency/digital conversion and, after multiplying this value with
SF and subracting OFF, outputs it at Y.
The hardware address of the analog input, from which the analog voltage
is to be read, is specified at input AD.

TRG - binary signal input via the front panel
The operating mode is set at input MOD.
MOD = 0 The integration time is the sampling time. A conversion is realized in each sampling time.
MOD = 1 Conversion is triggered via the "trigger" input TR.
The actual measuring time is terminated when the edge at TR goes from 0->1, the output
value is calculated and a new measuring time is started. The integration time is a multiple
of the sampling time. The first edge at TR after a reset starts the first measurement.
MOD = 2 Triggering by an external trigger signal.
The end of the current measuring time and the start of a new measuring time is
determined by an external signal. The last trigger signal, which was received between the
initialization mode and the start of the first system mode starts the first conversion (refer to
1 in the following diagram). The integration time is terminated by the last trigger signal
between two consecutive FB executions (refer to 2 in the following diagram). This means
that if several triggers are received between 2 consecutive FB executions, only the last is
effective and terminates the actual measuring time. The trigger signal is input via a plug
connector on the front panel of the module. If a trigger is simultaneously received when
the FB is being read-accessed, the trigger is suppressed and has no effect (refer to 3 in
the following diagram).
