Troubleshooting Honeywell Universal Modbus common problems

Error message or problem Description

You see the following error in the server The computer on which the Experion database software and server utilities run. See also: Experion server TPS. log file:

Error code 0106 (Device Timeout)

The server has not received a response from the controller Also known as remote terminal unit, RTU. A generic term for a device that is used to control and monitor one or more processes in field equipment. The most common control and monitoring device in an access control and security system is an access control panel. Other devices include security monitoring panels, elevator controllers, and fire monitoring devices. Controllers include programmable logic controllers (PLCs), loop controllers, bar code readers, and scientific analyzers. See also: C200 controller, control processor, CPM, hybrid controller, network node controller, PLC..

You see the following error in the server log file:

Error code 8102 (MODBUS error 2 - illegal data address)

You either specified an illegal address, or an illegal number of addresses.

You see the following error in the Station Experion's main operator interface. Station presents information using a series of displays. See also: display. Message Zone The line below Station's toolbar where explanatory messages and prompts appear. Compare: command zone. See also: Station. when you try to change the OP parameter Also known as point parameter. A unit of information about a point. For example, an analog point includes parameters such as process variable parameter (PV), output parameter (OP) and setpoint parameter (SP). See also: analog point, output parameter, point, process variable, setpoint parameter.:

CONTROL - Illegal mode for control of parameter

The point is in AUTO mode, or its equivalents (AUTO-LSP, CASC, AUTO-RSP). You must change the mode of the point to MAN or its equivalents (MAN-LSP, MAN-RSP).

You see the following error in the Quick Builder The Experion tool used to configure system components, such as standard points, Flex Stations, controllers (other than process controllers), electronic flow measurement (EFM), and printers. See also: controller, electronic flow measurement (EFM), Flex Station, process controller, standard point. output file:

Address is outside hardware cross reference table

You have upgraded your database from a previous server version and there is not enough room to store the controller addresses.

To rectify the problem, follow these steps:

  1. Make a backup of \server\data.

  2. Open a Command Prompt window and type:

    sysbld -PRESERVE -FULL

  3. Answer Y to the first two queries.

  4. When presented with the ability to change all sorts of database values, press ENTER until you see the following message:

    There are 8192 addresses per rtu. Enter required number of addresses

  5. Change the number of addresses per RTU Remote terminal unit. Also known as controller. A generic term for a device that is used to control and monitor one or more processes in field equipment. The most common control and monitoring device in an access control and security system is an access control panel. Other devices include security monitoring panels, elevator controllers, and fire monitoring devices. Controllers include programmable logic controllers (PLCs), loop controllers, bar code readers, and scientific analyzers. See also: C200 controller, control processor, CPM, hybrid controller, network node controller, PLC. (controller) to 32766.

  6. Keep pressing ENTER until the sysbld command terminates.

The address LOOP n SP The setpoint parameter of an analog point. The desired value of a process variable. Setpoint (SP) is an analog pointparameter, and the value is entered by the operator. The setpoint can be changed any number of times during a single process. The setpoint is represented in engineering units. See SP in the Control Builder Parameter Reference. See also: analog point, parameter, process variable. doesn't download.

The SP parameter is not a valid named address because there are a number of set point Also known as SP. The desired value of a process variable. Setpoint (SP) is an analog point parameter, and the value is entered by the operator. The setpoint can be changed any number of times during a single process. The setpoint is represented in engineering units. See SP in the Control Builder Parameter Reference. See also: analog point, parameter, process variable. types available, and a simple SP is ambiguous. WSP stands for working set point and SP1 stands for set point 1. In most cases, WSP works best.
