GENERAL

The XFL521B, 522B, 523B, and 524B modules are LONMARK compliant digital and analog I/O modules which can be installed at strategic locations within a building. These modules convert sensor readings and provide output signals used for operating actuators via L variables (SNVTs). Each Distributed I/O module plugs into a base terminal block allowing communication with controllers via the built-in Echelon minal block provides spring clamp terminals for easy connection of field cables from the various sensors and actuators.

The modular system allows Distributed I/O modules to be removed from the system without disturbing other modules. The module with terminal block mounts easily onto a DIN rail.

When using CARE, the Distributed I/O modules can be automatically bound and commissioned to the Excel 500 CPU (XC5010C, XC5210C, XCL5010) and XL50. When the modules are used by other controllers, provided plug-ins permit the modules to be commissioned by CARE 4.0 or by any LNS network management tool.

DISTRIBUTED I/O

INTEROPERABILITY

The Distributed I/O modules are compliant to the LONMARK Application Layer Interface Guidelines, version 3.2. The modules contain a L and setting the status of the various Sensor / Actuator Objects, as well as a L an Actuator Object for each individual output.

Upon receiving an update to the NViRequest network variable, the NVoStatus network variable is updated. The definition of SNVT_obj_request includes an object ID field to allow the Node Object to report status conditions for all objects on a node.

All network variables have the NV names in their self-documentation strings. This allows a network management node or tool to display meaningful information on a Distributed I/O module even if it is installed by an EXCEL 500 controller and not by the tool itself.

The Distributed I/O modules use the standard 6-byte location string (see Table 2) in the Neuron® chip’s EEPROM to store the module address (0...15 as set using the rotary HEX switch in the case of applications prior to CARE 4.0) and the module type.

the Distributed I/O module to set its location string. If a network management node commands this nci to “CFG_EXTERNAL”, then the module will no longer modify its Location String. This nci is stored in EEPROM and remains there even in the event of a power failure.

LONMARK Sensor/Actuator Objects

All Actuator Objects (contained in the output modules) have an output NV showing the actual state of the physical output and whether it is in the automatic or manual override mode. Note that the output modules have a manual override panel which can be plugged on or off.

All Sensor Objects (contained in the input modules) have a configuration property, MaxSendTime, defining the heartbeat time, i.e. the interval in which output NVs belonging to the physical inputs will be sent even if their values do not change.

All Sensor Objects also have a configuration property, MinSendTime, defining the minimum time which must elapse before a changed value of an output NV belonging to a physical input will be sent. This is to limit the network traffic when sensor values change rapidly.

Table 2. Location string for storing module address

The node self-documentation string contains the module type and revision in the optional part after the semicolon.

Example:

In this example, the module type is "XDO2" ("2" means that the 3120E5 chip is used) and the revision is "2.00".

LONMARK Node Object

Setting the Node Object to “DISABLE” via nviRequest suppresses updating of all output NVs and handling of input NVs. Setting the Node Object to “ENABLE” via nviRequest returns the module to normal operation.

The Node Object also contains the optional NV nciNetConfig which is initialized to “CFG_LOCAL” by default. This allows

This configuration variable is set to CFG_LOCAL at the factory and whenever the rotary HEX switch is reset. If it is set to CFG_EXTERNAL, a network manager will assign a network address for the node. In this case, the module will not modify its location string as long as the rotary HEX switch is not reset.

Points to a file directory in the address space of the Neuron® chip containing descriptors for the files in the module. It is used to access the configuration properties stored in configuration parameter files accessed by network management read/write messages.

Defines the minimum period of time between output variable transitions. This configuration property is applicable only to output NVs of the input modules.

Defines the maximum time period of time before output NVs are automatically updated. It must be set to a higher number than SCPTminSendTime. This configuration property is applicable only to output NVs of the input modules.

XFL52xB Module Response Times

The response time of Distributed I/O modules is defined as the period of time between the updating of the physical signal and the updating of the NV (or vice versa). The response time varies somewhat due to certain factors and is also dependent upon the module type (see also Table 4).

For each Sensor Object, the XFL521B Analog Input Module provides an additional output NV, SNVT_temp_p, which communicates the temperature in °C. This allows this module to be used as a true temperature sensor in an

ONMARK integration. If the Sensor Object is con-

nviValue SNVT_switch Receives the value for the output channel.

Transmits the feedback value of the actuator output. If the manual override switch is set to 0, or if the manual override module is not plugged in, the feedback output reflects the value of nviValue. As soon as the manual override switch is set at the 20% threshold, the Actuator Objects adopts this manual value. In this case, the value of nvoFeedback will be 0xFF (invalid) and the value field will contain the actuator position.

If the actuator is configured as a motor, the position commanded with the manual override switch will be reflected in the open/close commands for a floating actuator.

If the manual override switch is in the automatic position, data is transmitted whenever nviValue is written. If the manual override switch is in the manual position, data is transmitted whenever the manual position is changed.

Specifies the actuator output type for an output channel.

Specifies a floating actuator’s runtime from 100% to 0%.

Specifies a floating actuator’s runtime from 0% to 100%.

Specifies the delay time before a floating actuator changes its direction. This avoids mechanical problems that could occur when the run direction changes due to an update to nviValue while the actuator is still moving.

Specifies the delta level for an update to nviValue to be exceeded before a new position is calculated for the floating motor model. This is applicable only if the actuator is configured as a motor.

Specifies the lower synchronization threshold. If the actuator is configured as a motor and the value commanded through nviValue approaches 0%, the actuator is synchronized to 0% as soon as nviValue reaches the percentage specified by UCPTsyncMin.

Specifies the upper synchronization threshold. If the actuator is configured as a motor and the value commanded through nviValue approaches 100%, the actuator is synchronized to 100% as soon as nviValue reaches the percentage specified by UCPTsyncMax.

Specifies the additional runtime when an actuator performs a synchronization. This is to ensure that the actuator reaches the end position even if the actuator position is not what it should be due to inaccuracy.

For example, with UCPTsyncCharge at 100%, an actuator with a theoretical current position of 20% would be forced to run 120% of the runtime specified by UCPTdriveTimeClose if it starts a synchronization from this point of operation.
