It sends cyclically a time infarmation via the INSUM internal LON network to the connected field devices(MCU, ITS, PR112) on the same ICU. This enables the field devices to provide time stamped messages The System Clock works with the mcu devices version 2.1 onwards Support of clock setting functions via MMI is provided with INSUM Release 2.3. A software update of MMI Gateways and INSUM OS to Release 2. 3 is recommended if the System Clock is used 1.2 Objective This Manual describes the INSUM System Clock device functions, handling and functions. Further on it provides detailed information on the implementation of the system Clock into the INSUM System 1.3 Related documents ABB INSUM Documentation 1TGC 901007 B0201 INSUM Technical Information 1TGC 901021 M0201 INSUM MCU Users Guide 1TGC 901026 M0201 INSUM MCU Parameter Description 1TGC 901034 M0201 INSUM MMI Operating Instruction 1TGC 901030 M0201 INSUM MMI Quick Guide 1TGC 901042 M0201 INSUM Modbus Gateway Manual 1TGC 901052 M0201 INSUM Profibus Gateway Manual 1TGC 901060 M0201 INSUM Ethernet Gateway Manual 1TGC 901090 M0201 INSUM Control Access guide 1TGC 901091 M0201 INSUM Failsafe guide 1TGC 901092 M0201 INSUM Dual Redundancy Guide 1TGC 901093 M0201 INSUM Network Management Guide SACE RH 0080 Rey, PR112/ PD-L LON Works Interface v2.0 EP 407948 P0001 Users Manual Intelligent Tier Switch(ITS) Technical Documentation Hopf gmbH Germany: Technical Description -GPS Satellite Radio Controlled Clock 6870 System Information GPS 1TGC 901080 M0202 Edition July 2003 INSUMG System Clock Manual Notes 2 Operation 2.1 General The System Clock module can operate in two different modes depending an the kind of receiving/sending the time information. The respective modes are called Slave and Master and can be set via MM(from software version 2.3 onwards) The type of mode depends on the installation of the hardware and its function For Installation of hardware see chapter 3 2.2 Slave mode If the System Clock is configured as a Slave it gets the time information from a serial interface. In that mode an additional hardware is required, which provides the needed time information. On one hand, the Hopf GPs System 6870 can be used to ensures a very accurate time. The time base is synchronized by a global installed satellite system(GPs) On the other hand, for lower requirements on absolute accuracy, one System Clock in the switchgear can run in Master mode. The received time is changed into a domain wide broadcast LON NV and published to all connected subnets of one ICU backplane 2.3 Master mode If the System Clock is configured as a Master the device itself generates time information by using an internal RTC with lower accuracy. This infarmation is published as Nv and provided via RS422 additionally AB 1TGC 901080 M0202 Edition July 2003 INSUMG System Clock Manual Notes 3 Hardware Instalation 3.1 Hardware Characteristics The mechanical setup of the System Clock is like any other ICU component, mounted on the backplane plug-in type. The device has to be connected to one extension plate and draws power from the backplane P GPS config. o Receive error Sync pulse GPS active Service/Req. o Service/Stat AINSUM Clock Figure 1: System Clock Module Front Plate 3,2 Indications and Pushbutt System Clock Indications Power a green LED indicates that the 24 VDC-power supply for the module is available Receive error.

Do not change it if not necessary. If the device is started for the first time, it is running in Slave mode. After power up the clock starts with the last chosen mode 1TGC 901080 M0202 Edition July 2003 INSUM System Clock Manual Notes Hardware installation using Hopf GPS System 3. 4.1 Structure System Clock System Clock (Slave mode) (Slave mode MCU1/ MCU2/ MCU3/ MCU MCU1/ MCU2/ MCU3/ MCLA/ MCU 1/32 MCU2/32MCU3/32 MCU4/32MCU1: 32 MCU2:32MCU3/32 MCU4/32 ■RS422 time signal a Time synchronization signal (nvoClock) Figure 2: Hardware installation using Hopf GPS System 3.4.2 Description To get accurate time a GPS-System (Hopf GPS Satellite Radio Controlled Clock 6870, software version 11 hardware version RS232/RS422)is used. It consists of an antenna(installation with free view" over the horizon)and a receiver which is located in the switchroom and connected via coaxial cable (to the antenna). For further details on GPS and installation of Hopf devices refer to the Hopf document "System Information GPS Note: Only Hopf GPS-System is supported by the System Clock because it uses special features of that system(relating to: receiving the time, configuring the GPS-System The GPS System has a serial RS422 interface what is used for sending the data and receiving configuration information. For the pin layout of the system refer to document Technical Description -GPS Satellite radio controlled clock 6870 To connect the extemal Hopf GPS System to the backplane the following pin assignment is used Hopf GPS System Backplane 1 Backplane x Bus termination Slave mode) (Slave mode) at end of line Pin no Pin no Pin no GND 101GND 101 GND TXA 91 RXA 91 RXA 120Ohm 92RXB 92R×B RXA 111TXA n c 9 RXB 112 TXB n c Table 1: Pin assignment using GPS System If only one ICU is used there has to be one connection for parameterisation(Pin 111/112) and one for receiving the GPS time(Pin 91/92 )on the backplane If more than one backplane is used, on each of these one System Clock (in Slave Mode) has to be installed. Furthermore the receive pins of the respective backplane have to be connected accordingly ABB 1TGC 901080 M0202 Edition July 2003 INSUMG System Clock Manual Notes Note: Only one System Clock must have a connection to parameterise the GPs System. It is recommended to use the module near the gPs receiver module. the maximum number of system Clock modules is 32 whereby the last one has to get a bus termination for RS422. The RS422 lines have to have a maximum length of 500m whereas the sum of all stub lengths is max 660m 3.5 Hardware installation without GPS System 3.5.1 Structure Backplane (Master modc) MCU1/ MCL3/ MCU MCUl/ HMo」 MCU/ MCU/ Cu1/2 MCU2/32 MCI3/32 MCI4/32 1CU1/37 MCU2/32 MCU4 32 ■RS422 time signal L Time synchronization signal (nvo Clock Figure 3: Hardware installation without GPS System 3.5.2 Description If the requirement to the absolute accuracy is low the internal Rtc of the System Clock can be used to provide the system with the time information. In that case one System Clock has to run in Master mode If only one IC is in use, no additional wiring is necessary for that backplane more than one backplane is used, the System Clock offers the possibility to distribute the generated time information via RS422 to enable other System Clocks (in Slave mode) to process the sent time. In that case, on each of these backplanes a System Clock (in Slave mode) has to be installed. Furthermore the transmit pins(111/112)of the backplane containing the sending System Clock have to be connected to the receive pins (91/92) of the respective backplanes.
