Environment and Enclosure

This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC 60664-1), at altitudes up to 2000 m (6562 ft) without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR 11. Without appropriate precautions, there may be difficulties with electromagnetic compatibility in residential and other environments due to conducted and radiated disturbances. This equipment is supplied as open-type equipment. It must be mounted within an enclosure that is suitably designed for those specific environmental conditions that will be present and appropriately designed to prevent personal injury resulting from accessibility to live parts. The enclosure must have suitable flame-retardant properties to prevent or minimize the spread of flame, complying with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if non-metallic. The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this publication may contain additional information regarding specific enclosure type ratings that are required to comply with certain product safety certifications. In addition to this publication, see:

• Industrial Automation Wiring and Grounding Guidelines, for additional

installation requirements, Allen-Bradley publication 1770-4.1

• NEMA Standards 250 and IEC 60529, as applicable, for explanations of

the degrees of protection provided by different types of enclosure.

This product is grounded through the DIN rail to chassis ground. Use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding. Secure DIN rail to mounting surface approximately every 200 mm (7.8 in.) and use end-anchors appropriately.

1797-IE8 and 1797-IE8NF Field Transmitter Supply Characteristic

The field transmitter supply can be modeled as a 21.5V source with a 273 Ω series resistance. (See the following graph.) This provides a simple and useful mechanism to determine transmitter and loop compatibility.

The actual transmitter supply contains three ranges of impedance with the following characteristics:

• The output voltage is ≈ 21.5V for load currents of 0 mA.

• If the load is more than ≈ 680 Ω but less than ∞Ω, the transmitter supply is in a constant resistance region (≈ 273 Ω).

• For load impedance between 0 and ≈ 680 Ω, the transmitter supply

current is in constant current mode (≈ 22 mA).

If an intrinsic safety fault occurs in the field transmitter supply of any channel, every channel’s field transmitter power is shutdown.

The following graph depicts the typical transmitter load characteristic.

The normal module field side power consumption is 7.5 W when all channel

21.5V sources (+) are loaded. If field devices are used that are powered separately, the module field-side power consumption can be determined by Field_Side_Power = 9.5V x (300 mA + n x 55 mA). Where n is the number of field devices that are supplied by the 1797-IE8 or 1797-IE8NF.

Field Descriptions

Analog Input Data Specifies the value of the analog input data from the module. Specific

format is controlled by Module Data Format Control parameter. This data is used when the channel is in analog input mode.

Overrange Alarm Alarm signal for input overrange. This signal is always active.

Range: 0 = normal, 1 = input overrange

Underrange Alarm Alarm signal for input underrange. This signal is always active.

Range: 0 = normal, 1 = input underrange

Remote Fault Alarm Alarm from remote transmitter, indicating transmitter difficulties,

Local Fault Alarm Alarm indicating the loop to the transmitter, or, if there is no transmitter,

sensor difficulties, or loop to the sensor is open. If not using a remote transmitter, this alarm can be used as a high-high or low-low alarm. Depending on Data Format, these current values may be indicated by percent, mA, or integer values. Range: 0 = normal, 1 = fault detected

the loop is open or shorted. When active, this alarm triggers at 2 mA and 22 mA for open and short respectively. Depending on Data Format, these current values may be indicated by percent, mA, or integer values. Range: 0 = normal, 1 = fault detected

The HART Rebuild bit will trigger a HART Rebuild on a transition from 0 to 1. The HART Rebuild bit must remain 1 for HART communications to function after the rebuild completes. If the HART Rebuild bit is set to 0, HART communications are disabled.

During the time the system is rebuilding the HART table, the HART rebuild flag is set. Range: 0 = normal, 1 = HART rebuilding

A 1 indicates that HART communications are failing on the associated channel. Range: 0 = normal, 1 = HART communication failure

When this bit is set (1), it indicates that HART communications are failing on the associated channel. Range: 0 = normal, 1 = HART communication fault

Square Root Threshold (1797-IE8H)

Extended Configuration (1797-IE8H)

The HART Read Back bits show deviations between the analog measured current value on a loop (by the 1797-IE8H) and the digital real current (sensed by the HART device on its own) received by the 1797-IE8H during HART communication in the background. This functionality can be turned on by defining a HART Readback Threshold greater than 0. See 1797-IE8H CE, CENELEC I/O Entity Parameters

page 42. This functionality is used to recognize loop errors whereby a

parasitic current is bypassing the 1797-IE8H. Range: 0 = normal, 1 = HART Readback threshold is exceeded.

Delivers the percentage value (in steps of 1%) of the threshold for forcing the HART read back indication (input signal deviation HART/Analog) with a 31% maximum deviation. If there is no HART transmitter on the loop or the loop is not in the transmitter list, the function is switched off internally in the I/O module. Range: 0 = disabled, 1…4 = not supported from I/O module (set to 5 internally), 5…31 = percentage threshold data (5…31%).

Range: 0 = normal, 1 = HART communication is currently occurring.

When this bit is set (1), it indicates that a HART field device was found during the rebuild sequence on the associated channel. Range: 0 = transmitter was not found, 1 = HART transmitter was found.

This setting affects all channels using Data Format 2 or 6. It sets low, end-of-scale percent value at which square roots start being reported. Below this level 0% is reported. This compensates for asymptotic values of the square-root function as the input approaches 0. Range: 0 = disabled, 1 = 2%, 2 = 5%, 3 = 10%

Configuration additions are needed for HART communications in Series A mode. An extended configuration area is provided. This Extended Configuration table is configured by writing a CIO or MSG instruction with the following:

Class = 0x7D Instance = Product location on flexbus (Use 1 for the module located next to the adapter.) Attribute = 0x65 Service = Set Attribute Single (0x10)

Cyclic HART Input Data

The HART input data holds the primary variables for the "live" HART device, and other information gathered during the normal HART scan. Additional "documentary" data is available through the pass through message interface in the device information tables. Pass through messages are defined in detail in the User Manual.

The HART Input Data for a channel may be zeroes if HART communications is disabled for that channel. For more information on disabling HART communications, refer to the Disable HART communications and HART Disable functions in the Configuration Map table.
