Ethernet Transmitted Modbus-TCP Errors
An accumulator that indicates the number of errors that have occurred while the PL1000E was attempting to transmit a modbus message over the Ethernet port. Transmitted errors can indicate incorrect or faulty system wiring or incorrect Ethernet configuration. The accumulator value is reset to zero each time that the PL1000E has the power removed and then has the power turned back on. The accumulator value is not a lifetime total. If power to the PL1000E is left on for an extended amount of time, then the accumulator value can roll over and will begin to increment from zero once again.Sample Message:
Request from Modbus Master 15 03 00 60 00 02
Response from PL1000E Slave 15 03 04 00 00 00 00
Data = 0 errors
Scale = 1 transmit error/bitNumber of Modbus-TCP Connections
The number of modbus TCP connections that are currently recognized by the PL1000E.Sample Message:
Request from Modbus Master 15 03 00 62 00 01
Response from PL1000E Slave 15 03 02 00 01
Data = 1 Modbus TCP Connection
Scale = 1 Modbus TCP Connection / bitECM Mapping
The ECM mapping registers contain a summary of the parameter translation (PCL) file that is currently loaded into the PL1000E. Each mapping contains:
A pair of ECM's, that is, a "FROM ECM" and a "TO ECM"
The ECM type
The PL1000E port that is used to communicate to the ECMThe ECM mapping modbus registers are capable of containing a configuration summary for up to 15 pairs of ECM's for a maximum total of 90 registers.The following example shows a configuration for a parameter translation from three ECM's, that are on Cat Data Link, to a "Modbus Master" that is communicating with the PL1000E on RS-232 port 1. The PL1000E is configured with a "Modbus Slave" at address of 0x10 on RS232 Port 1.
Engine Controller (CDL address 0x24)
ICSM#1 (CDL address 0x6D)
ICSM#2 (CDL Address 0x6E)
To: Modbus Master on RS-232 Port 1Note: The default "Status Registers" and the "Parameter Translation Registers" are located at different modbus slave addresses on the same physical port. Refer to the "Object - Modbus ECM" section that is located within the "Parameter Translation Configuration". The "Object - Modbus ECM"section contains information on assigning the appropriate modbus slave address for "Parameter Translation Registers".Sample Message:
