Configuring the ETM with the Electronic Modular Control Panel (EMCP)
Reference: For more detailed information, refer to Systems Operation, Troubleshooting, Testing and Adjusting, RENR7902, "EMCP 3 Control Panel".
Reference: For more detailed information, refer to Application and Installation Guide, LEBE5255, "EMCP 3.1, 3.2, 3.3 Generator Set Control A & I Guide"
The ETM broadcasts standard SAE J1939 Parameter Group Numbers (PGN) and Suspect Parameter Numbers (SPN) on the J1939 CAN Data link.
Note: Only EMCP 3.3 and higher are compatible with the standard SAE J1939 CAN data link that is used by the ETM. EMCP 3.1 or EMCP 3.2 will not communicate with the J1939 CAN data link that is used by the ETM.
Set up the EMCP 3.3 module in order to display the engine exhaust temperatures which are broadcast by the ETM.
Perform the following procedures in order for the EMCP 3.3 to display the cylinder temperatures.
- Scroll through the following screens on the EMCP 3.3:
- Main menu
- Configure
- Setpoints
- Engine monitor/protect
- Enhanced engine monitor
- Set the "Engine Cylinder Temperature Sensor Install Status" to "Installed".
- Set the number of engine cylinders to correspond with the number of cylinders on the engine.
- Verify functionality by pressing the ENGINE OVERVIEW button followed by the DOWN arrow button. The cylinder temperatures should be displayed toward the bottom of the list.
Note: Asterisks **** displayed on the EMCP 3.3 screen indicates that either the configuration settings are incorrect or that the EMCP 3.3 is not programmed to display the information it is receiving from an external module such as the ETM.
First recheck the setup steps in order to ensure that all steps were correctly completed and that the configuration settings are correct. If asterisks are still present but everything else is functioning normally, the EMCP 3.3 may not be programmed for the additional ETM data which is being broadcast. In this case, the information broadcast from the ETM will be available on the LCD on the front of the ETM.
Configuring the ETM with the Advisor Panel
The ETM broadcasts standard SAE J1939 PGN and SPN on the J1939 CAN Data link. If a Caterpillar Advisor Module is connected to the J1939 CAN network, for instance, an Advisor Panel on a G3500 engine, the Advisor Panel will automatically display exhaust cylinder temperatures without changing any parameters on the Advisor Panel.
Note: Asterisks **** displayed on the advisor screen indicates that either the configuration settings are incorrect or that the advisor is not programmed to display the information it is receiving from an external module such as the ETM.
First recheck the setup steps in order to ensure that all steps were correctly completed and that the configuration settings are correct. If asterisks are still present but everything else is functioning normally, the advisor may not have the correct version of software or may not be programmed for the additional ETM data which is being broadcast. In this case, the information broadcast from the ETM will be available on the LCD display on the front of the ETM.
RS-485 Datalink and Communication
The ETM is part of a system that has been designed in order to interface with popular computers, terminals, and programmable controllers. The serial communications are compliant to the Modicon Modbus RTU standard. This standard uses RS-485 for the hardware communication format.
A serial RS-485 data link allows communication between a "Master" and a "Slave" unit.
Master-Slave Circuit Operation
The ETM's RS-485 communication system is designed as a master-slave circuit. Each unit responds to a unique node number only after the unit is interrogated by the master computer. The units communicate with the master via a polling system. The master sends a command and only the polled slave responds. The slave modules can never initiate a communications sequence. A simple command and response communication protocol must be strictly observed. The slave is the 195-0383 Pyrometer Gp. This remote terminal unit does not have the capability to communicate over the J1939 CAN data link. The 195-0383 Pyrometer Gp is designed to communicate over the RS-485 data link.
The node number is used in the system in order to identify the desired slave unit being polled. The node number can be any numeric value from 1 to 99. The range of numbers (1 to 99) is allowed in order to group devices by a function or by an application. The first digit can be used as the group or engine number and the second digit as the unit number. For example, 53 could be used to identify the number 3 slave unit mounted on engine number 5.
The RS-485 system uses two wires for communication. The system can only send data or the system can receive data at one time over the same two wires. When the master is in the transmit mode, the slave is in the receive mode. When the slave is in the transmit mode, the master is in the receive mode.
RS-485 is a communications standard that is used in order to satisfy the need for multi-dropped systems that can operate at high speeds over long distances. RS-485 uses a balanced differential pair of wires that switch from 0 to 5 volts in order to communicate data. RS-485 drivers can handle common mode voltages from −7 to +12 volts without loss of data.
The following parameters must be set by the master in order to communicate with the slave:
- Baud rate: 9600
- Data bits: 8
- Stop bits: 1
- Parity: None
Every slave unit has a direct connection to the master. This allows any slave unit to be removed from service without affecting the operation of the other units. Every unit must be programmed with a unique address or node number, but the addition of new units or nodes can be in any order. To minimize unwanted reflections on the transmission line, arrange the bus as a trunk line going from one module to the next. Avoid random structures of the transmission line. Special care must be taken with long busses (500 feet or more) in order to ensure error free operation. Long busses must be terminated with a 120 ohm resistor between the terminals marked RS-485 A (pin 70) and RS-485 B (pin 69) at the master only. Use twisted pair shielded cable in order to enhance signal fidelity. In order to prevent ground loops, the shield must be connected to the shield terminal at the master only.
When connecting the ETM to the RS-232 port on a PC, an RS-232 to RS-485 converter must be used for the communication interface.
Illustration 1 | g01473834 |
RS-485 uses a balanced differential pair of wires that switch from 0 to 5 volts in order to communicate data. In situations where many units (32 max) are connected together on a long run, voltage drop on the communications leads becomes a major problem. Voltage drops on the RS-485 minus lead appear as a common mode voltage to the receivers. While the receivers are rated to a maximum voltage difference of ±7 volts (−7V to +12V), a practical system should not have a voltage difference exceeding ±3 volts under normal conditions. The wire gauge used for the connections therefore limits the maximum number of units or the maximum length of wire between units in each application. The following formula can be used as a guideline to select the appropriate wire gauge.
- For 18 AWG wire, the number of units equals 4000 per feet of wire used
- For 20 AWG wire, the number of units equals 2500 per feet of wire used
- For 22 AWG wire, the number of units equals 1600 per feet of wire used
Note: The maximum number of units connected together in a system is 32.
Modbus communications are as follows:
- The maximum number of registers that can be read at one time is limited to 32.
- The maximum number of booleans that can be read at one time is limited to 256.
- All communications are at 9600 baud, 8 Data bits, No Parity, 1 Stop bit (9600 8N1).
Note: All temperatures are stated in 0.1 Degree Kelvin (for universal compatibility). A register value of 2730 is 273.0 degree K, which is 0 degree C, or 32 degree F.

- C = Degrees C
- F = Degrees F
- NO = Normally open
- NC = Normally closed
- CYL = Cylinder
- H = High
- LO = Low
- TMP = Temperature
- DEV = Deviation from average
- TO = Turbocharger outlet
- TI = Turbocharger inlet
- ACK = Acknowledge
- TC = Thermocouple
- OOR = Out of range
- DIF = Differential
- L = Latched
- NL = Not latched
- ARM = Arming
- ALM = Alarm
- InStat = Input status
