Page 171 Communications Introduction 4.1. GEM 80-400 Controllers may transfer and receive controller memory data using serial communications links. The serial ports can be used for the following types of application: Operating the GEM 80-400 Controller as part of a distributed controller network, i.e.
Page 172 Figure 4.1 - Serial Port Connections Note...In the case of GEM 80-400 Enhanced Controllers, further serial ports can be added using Fast I/O Serial Communications Modules and/or STARNET Modules. See the relevant User Information Sheets for connection details. 4.1.1. Connecting Serial Ports 1 and 2 Serial Ports 1 and 2 produce RS232 and RS485 format signals.
Page 173 Figure 4.2 - Serial Ports (Ports 1 and 2) Pinouts The RS232 output from Port 1 or 2 may be converted to 20mA current loop using a suitable active converter. GEM 80-400 to other GEM 80 Controllers 4.2. Some GEM 80 controllers other than the GEM 80-400 provide a form of 'RS422' serial links.
Page 174 4.2.1. Communication Protocols The GEM 80-400 Controllers have a built-in facility for communicating with other GEM 80 equipment using a communication protocol called ESP (Extended Simple Protocol). ESP enables a GEM 80-400 Controller to transmit and receive the contents of up to 128 data tables at any one time through a serial communications link to other GEM 80 controllers.
Page 175 Ports 1, 2 and 3 are configured by presetting data in the P-data table, and then entering a RECOMPILE command (powering down is not required). The type of serial port is determined by the value entered in P11 for Port 1, P31 for Port 2 or P51 for Port 3, and the function of the rest of the P-table locations is dependant upon this value.

Page 183 terminal or VDU terminal. It performs the functions of auto-echoing and line editing without the need for user programming. The terminal is expected to have the following characteristics (ASCII character names are shown in parentheses): Pressing the carriage-return key generates @0D (CR). Pressing the Delete/Rub out key generates @7F (DEL).
Page 184 replaced in the line buffer with @FF and is echoed back to the VDU as SUB. Thus, if the VDU displays an upside-down question mark for SUB (@1A), the operator will be able to back space to any symbol of this type on the line and overkey the character to re-transmit it to the printer/Keyboard Port.
Page 185 To furnish the user program with information regarding the state of the output buffer, two flags called the 'empty flag' and the 'filling flag' are provided. The empty flag is set ON between program scans when the cyclic buffer is empty and all characters have been transmitted.
Page 186 to the message area of the P-table the messages will be moved and the extra P-table created filled with zeros. The quantity of messages that can be stored in a system is restricted only by the memory occupied by data tables and the user program. Remember that data table P2 contains the length of the preset message area in bytes and is therefore limited to the maximum number that can be stored.
Page 187 After loading a program containing messages, the program must be compiled before using the editor. The editor cannot be entered until this has been done.

Page 253 GEM80-400 8. Commissioning Commissioning Introduction 8.1. Your GEM 80 controller and I/O will have to be configured to meet your particular requirements. It is extremely unlikely that these requirements are the same as those of other GEM 80 customers. Therefore, we can only give you general commissioning procedures rather than specific ones for your particular system.
Page 254 8. Commissioning GEM80-400 These will allow you to write test programs for checking out the equipment. In addition, you will need User Information Sheets or Technical Manuals, depending on your system configuration, for: Basic I/O Modules Verification I/O Modules and, optionally, in the case of Enhanced Controller systems: Fast I/O Modules Extra Central Highway Modules (such as IMAGEM videos, GEMLAN-D Modules,...

Page 259 GEM80-400 8. Commissioning Basic and Verification I/O Logic Input Checks 8.10. A GEM 80 series controller will only scan I/O addresses that are referred to in the user ladder program. You can therefore begin by putting in a rung which contains a number of A-table references and outputs to an internal trash can workspace table location (e.g.
Page 260 8. Commissioning GEM80-400 (14) Check that each input state can be seen to change on the programming tool screen when the corresponding plant device is operated. (15) Check also each input by LED indication on the module front panel. If checks (14) and (15) both fail for an input device, you may have: a cable terminated on a wrong terminal or wrong module.
Page 261 GEM80-400 8. Commissioning Fast I/O Input Checks 8.12. If your controller does not include any Fast I/O Input Modules, skip to the 'Connecting Output Equipment' section of this chapter. Switch OFF those power modules that feed the processor subrack and any separate Fast I/O subrack.

Page 263 GEM80-400 8. Commissioning Connecting Output Equipment 8.14. Once you have checked the outputs and found them to operate correctly without plant-side power, the next stage in the commissioning procedure is to connect the plant-side power to them. Check that each output device responds to the controller in an appropriate manner, e.g.
Page 264 8. Commissioning GEM80-400 Note...The Tx LEDs on the processor module, when it is configured as a Control Port, light when it attempts to transmit, even if no serial link connections are made. There are several types of serial link. To keep this chapter reasonably brief, we cannot tell you in detail how to commission every individual type.
Page 265 GEM80-400 8. Commissioning For user-controlled serial link, you will also need to set values and bits in appropriate locations in I-table to initiate transmission, or to set message destinations.

Page 269 Batteries 9.4. 9.4.1. General The battery life times depend on the proportion of time that the battery is supporting memory, and mains power is switched off. The GEM 80-400 Processor Module memory is supported by a 950mA/H lithium/manganese dioxide battery, which has a typical shelf-life of 6 years (4 years minimum) and a typical support life, after one year powered up, of 9 weeks minimum at 70°C or 47 weeks minimum at 40°C.
Page 270 9.4.3. Battery Replacement Procedure Note...The system should be powered up while the battery is being changed to prevent the contents of the memory, i.e. user program and data tables, being lost.

Page 280 When compilation is attempted the program will not run if any forbidden addresses have been used in the program, and the programming tool will display a diagnostic message. Forbidden addresses are where A-table and B-table addresses have the same number (e.g. A4 and B4) or where addresses have a number greater than the maximum imposed by the hardware, i.e.
Page 281 It should be noted that if the only reference to a B-table, or the only reference to a Fast I/O Module, is deleted from a program and a recompilation performed, the I/O hardware associated with that table will no longer be scanned. This could result in outputs being left in an uncontrolled state until the next power up.

Watchdog and Safety Circuits Introduction 11.1. Power, 0V, and watchdog terminals are located on the backplane terminal boards which are shown in Figures 1.12 to 1.15. A safety earth stud is fitted to the terminal bracket. Safety earth studs are also located on the subrack side cheeks at the rear of the mains input filter.
Page 307: Safety Earth Connections
Safety Earth Connections 11.2. Figure 11.1 - Location of Safety Earth Studs Safety earth studs are located on the subrack side panels at either end of the subrack. The equipment must be earthed by a secure safety earth connection of 2.5mm² minimum cross-sectional area. Watchdog Contacts 11.3.
Page 308: Typical Watchdog Circuits
The watchdog contact terminals of the Standard Controller are located on W/D, two watchdog circuit push-on terminals on the lower backplane. The watchdog contact terminals of the Enhanced Controller are located on TB1, the Terminal Block on the lower backplane. See Figure 11.2 for details of both controller connections.

Method (1) allows suppression of several outputs of different voltage levels with a single contact. This relies on the electronic circuitry of each module working correctly. Therefore, for ultimate safety, where outputs operate moving machinery or otherwise provide a personnel hazard, Method (2) should be used with one contact for each plant-side power voltage.
