ESD guidelines
Modules containing electrostatic sensitive devices (ESDs) can be identified by the
following label:
Strictly follow the guidelines mentioned below when handling modules which are sensitive
to ESD:
• Always discharge your body's static electricity before handling modules which
are sensitive to ESD (for example,
by touching a grounded object).
• All devices and tools must be free of static charge.
• Always pull the mains connector and disconnect the battery before you install
or remove modules which are sensitive to ESD.
• Handle modules fitted with ESDs by their edges only.
Modern automation systems consist of a variety of computers, controllers and
systems that exchange data with one another. For real-time operation of such
plants, it is essential that the times of all components are synchronous. This
applies especially for error tracing, when event messages receive a time stamp
and when cause and effect have to be identified through a reliable chronological
sequence.
As plant central clock, SICLOCK TC 400 supplies the various plant components
with the exact and reliable time, which is obtained from one or more external synchronizations with an official or legal time, usually GPS or DCF77 radio clocks.
The time is distributed via Ethernet, and also via point-to-point outputs.
Note
Use only one device as plant central clock to supply the time to all components
throughout the plant.
Exception: redundant operation of the plant central clock.
The following figure shows a connection example of the SICLOCK TC 400 to a
SICLOCK GPS1000 as radio clock and an NTP server as an additional external
synchronization.
SICLOCK TC 400 can be matched to the local official time or GMT via external
synchronization in order to automate or restrict manual actions, such as daylight
saving time switchovers and leap seconds, to a minimum.
External synchronizations can be GPS or DCF77 radio clocks, servers (e.g. time
signal from an NTP server), further SICLOCK TC 400 devices or other signal
sources. They are connected to RADIO CLOCK 1 or RADIO CLOCK 2 or to one
of the four Ethernet ports on the device.
NTP servers are supported as external synchronization on the Ethernet ports.
Possible radio clocks to RADIO CLOCK 1 and RADIO CLOCK 2:
• SICLOCK GPS1000
• SICLOCK GPSDEC
• SICLOCK DCFRS
Third-party products can be connected via TTY (passive). The following protocols
are supported:
Description
• Demodulated DCF77
• Serial:
Further information
Linking the external synchronization (Section 9.1)
Various functions are available in SICLOCK TC 400 in order to generate the time
valid for the plant from the external synchronization. This includes setting options
for time zones as well as the parameterizable daylight saving time.
Time assurance through protected synchronization
If a discontinuity of more than 5 s occurs in the external synchronization, the protected synchronization is activated and, for safety reasons, the synchronization
not performed.
Time assurance through microstepping mode
A time difference between the external synchronization and the device, which can
occur through a temporary radio failure or switchover to a substitute synchronization, is automatically cleared unnoticeably in microstepping mode for the plant
operation. There is no inconsistency in the time.
Further information and parameterization options for protected synchronization
and the microstepping mode are described in Section Synchronization
(Section 9.3.2).
Note
Only parameterize the plant time at one location within the synchronization hierarchy, ideally at the plant central clock.
2.5Commissioning
The commissioning can be divided into the following steps:
1. Installation (Section 5)
2. Connecting (Section 6)
3. Assigning IP address on the device
Parameterization and Operation on the Device (Section 8)
4. Parameterization (Section 9)
With a few exceptions, the settings are made with the configuration tool, see
Configuration Tool (Section 7).
Up to two radio clocks and up to four time servers can be operated on the
SICLOCK TC 400 for the external synchronization.
The priorities of the external synchronizations and therefore the redundancy
behavior can be set via parameters, see Redundancy (Section 9.1.3).
Redundant SICLOCK TC 400 plant central clock
A SICLOCK TC 400 can be operated via various ports on a redundant network
and several SICLOCK TC 400 can be operated as servers on one network.
For further information, refer to Chapters Configuration Tool (Section 7) and
Parameter Table (Section 10).
Redundant control of time receivers (output redundancy)
Description
At least two SICLOCK TC 400 are used for an output redundancy. With the appropriate parameterization, OUTPUTs 1 and 2 of the two devices can each be connected redundantly with the other.
For further information, refer to Sections Redundant point-to-point connec-tions (Section 6.4.2) and OUTPUT 1 and 2 redundant (Section 9.2.4).
The front panel shows the current mode in the display and with LEDs. The device
can be operated directly via the keypad. A Web-based configuration tool is available for a wide range of configuration options, see Configuration Tool
(Section 7).
SICLOCK TC 400 has been designed for weather-protected, stationary operation
in an industrial environment.
The operating conditions surpass the requirements according to DIN IEC 607213-3:
• Class 3M3 (mechanical requirements)
• Class 3K3 (climatic requirements)
General information about operation
Caution
The device is approved for operation in closed rooms only. The guarantee is void
if this stipulation is ignored.
Condensation
When transporting the device at low temperatures, ensure that no moisture forms
on or in the device. This also applies if the device is subjected to extreme changes
in temperature.
Commissioning
Allow the device to slowly adjust to room temperature before commissioning. Do
not place the device near heat radiation. With large differences in temperature,
harmful condensation can be avoided by leaving the device in the transport packaging.
If condensation occurs, wait at least about 12 hours before you switch on the
device (for 20° C temperature difference). The waiting period is extended accordingly for greater temperature differences.
Avoid extreme ambient conditions. Protect your device against dust, moisture and
heat. For further information, see Chapter Technical Data (Section 13).
Use in residential areas and operation in the public network
If you operate the SICLOCK TC 400 in residential areas or in the public network,
you must ensure that it complies with the limit class B according to EN 55022 with
regard to the emission of radio interference.
Note
This is a a class A device. The device may cause RF interference in residential
areas or in the public network. In this case, the operator company may be held
liable for taking appropriate measures.
The following measures are recommended to ensure the interference complies
with limit class B:
• Installation of the SICLOCK TC 400 in grounded control cabinets / control
boxes
• Use of filters in electrical supply lines
