GEMTEQ I/O 2. Introduction to CAN Networks INTRODUCTION The GEMCAN network is based on the CANopen communication model and uses standard CAN hardware and cabling. The CANopen standard consists of an addressing scheme, several small communication protocols and an application layer defined by a device profile. The communication protocols have support for network management, device monitoring and communication between nodes.
GEMTEQ I/O 2. Introduction to CAN Networks Slave GEMTEQ modules have a fixed size and number of PDO’s assigned to each module. There are 16 C/D tables (a maximum of 4 transmit and receive PDO’s) per node ID. Any configuration data for the module is included within the 16 words of output PDO data, the GEMTEQ network does not use SDO’s to configure slave modules.
GEMTEQ I/O 3. GEM80 GEMCAN NETWORK GEM80 GEMCAN NETWORK INTRODUCTION A GEMCAN network operates on a Master / Slave principle, with a single Master and multiple Slaves. Although a second Master may be connected to the network, only one Master is active at any one time.

GEMTEQ I/O 6. GEMTEQ I/O Modules MODULE CONFIGURATION Before a GEMTEQ I/O module may be connected to the GEMCAN network, the following two items must be setup on the module. • Node ID • Baud Rate 6.3.1 Node ID Each device on a GEMCAN network must have a unique Node ID. This is setup on the hexadecimal rotary switches SW3 and SW4, as detailed below.
GEMTEQ I/O 6. GEMTEQ I/O Modules 6.3.2 Baud Rate The baud rate is selected by the hexadecimal rotary switch SW5, see Table 6-3. All devices on a GEMCAN network should have the same Baud Rate selection. Table 6-3 GEMTEQ I/O Module - Baud Rate Selection Value Baud Rate Maximum Bus Length (m)
GEMTEQ I/O 6. GEMTEQ I/O Modules If the GEMTEQ I/O module is fitted to the end of a GEMCAN network, then they should be wired up as per Figure 6-2. CAN L CAN H (Fit Link for Network Termination) Figure 6-2 CAN Network Connections –...
GEMTEQ I/O 6. GEMTEQ I/O Modules MODULE DIAGNOSTICS Each GEMTEQ I/O module is fitted with a comprehensive set of diagnostics LEDs, to help with rapid system fault finding. Details of the LED locations can be found in the appropriate module Instruction Sheet.
GEMTEQ I/O 6. GEMTEQ I/O Modules APPLICATION CONFIGURATION DATA GEMTEQ modules can be configured by the application code within the GEM80-500 Controller. Configuration data is sent to an individual module using the appropriate "D" table for that module. This is achieved by transmitting data to the GEMTEQ I/O module via the GEMCAN network using an output PDO.
GEMTEQ I/O 6. GEMTEQ I/O Modules 6.6.3.1 Freeze/Fallback Timeout (mS) Range 1 to 32000 mS 0 = 500 mS (Default) If the application requires the default freeze/fallback time to be overridden then a value can be transmitted to the module in the Freeze/Fallback Time. For further details please refer to the appropriate Instruction Sheet.
The complete consignment should be checked against the delivery note for any loss in transit. 7.1.2 What to do if something is missing or damaged If any damage has occurred, or any parts are missing, CONVERTEAM Kidsgrove, should be contacted immediately and the following details quoted: (1) List of damaged or missing items;...
GEMTEQ I/O 7. Installation and Commissioning STORING GEM80 EQUIPMENT BEFORE INSTALLATION 7.2.1 Environmental Conditions and Protection Equipment which is not required for immediate installation should be stored in a clean, dry atmosphere at a reasonably constant temperature (-20 to +70°C). To minimise the ingress of fine dust, the equipment should be kept in the original packing, which should be re-sealed after the delivery inspection.
Because these requirements vary for each GEM80 application this section of the manual only includes general commissioning guidance about the method to be followed. The instructions required for each application should be discussed with CONVERTEAM or an approved System Builder.
GEMTEQ I/O 7. Installation and Commissioning 7.4.4 Radio Frequency Interference (RFI) This clause is intended as a guide for users who wish to operate GEM80 equipment in the vicinity of a radio transmitter. The transmitter may be of the static or the hand-held portable type. Unrestricted use of a transmitting device could result in a malfunction of the equipment.
GEMTEQ I/O 8. Maintenance and Fault Finding MAINTENANCE AND FAULT FINDING GENERAL GUIDANCE FOR MAINTENANCE This section includes general guidance for the upkeep and maintenance of a system containing GEMCAN I/O Scanners and GEMTEQ I/O modules and includes fault finding information which can be used in the event of either an in-service fault or faults which occur because of ladder program development.

GEMTEQ I/O 8. Maintenance and Fault Finding 8.3.3 Output PDO Fault Data The Input PDO Fault Data consists of two words per slave device. For network A and B there is 1-bit allocated for each word of input data. Bits will only be seen for network B if a Redundant Master has been configured.
However, some materials require special consideration during disposal e.g. the battery which is a Lithium Thionyl Chloride type. It is recommended that the controller be returned to Converteam for safe disposal. Prior arrangements should be made for return to the address at Section 8.5. Alternatively the controller may be returned to the nearest Converteam service centre.
