Product Specifications

2 Product Specifications

2.1 Overview and Application

The FieldConnex® Multi-Input/Output device (MIO) for FOUNDATION Fieldbus provides discrete inputs, discrete outputs, 1 frequency input, and 1 counter to process control systems. The device is is suitable for DIN rail mounting and field installation with different housing options. The F2 type housing is made of sturdy cast aluminum for installation in rough environments. Fieldbus and sensor-actuator cable entries can be selected individually from a range of cable glands. Optionally, either screw terminals or spring terminals can be chosen. Contact your Pepperl+Fuchs representative for further information on housing options.

The device can be installed in hazardous areas Zones 1, 21, 2, 22, and Division 1, 2. FOUNDATION Fieldbus and input/output sensor and actuator connections are rated intrinsically safe for installation in Zone 0 and Division 1.

The device provides different configurable modes of operation.

The valve coupler mode allows connecting 4 low-power valves with 2 end position inputs per valve.

The sensor input mode allows connecting up to 12 binary sensors. 4 sensor inputs are designed to support vibrating forks for level control. In frequency mode, 1 frequency input and 8 discrete inputs are provided. In counter input mode, 1 counter input and 8 discrete sensor input modes are provided.

The MIO is intended to be used as a replacement for Pepperl+Fuchs process interface FD0VC-Ex4.FF.

2.2 Modes of Operation

The device supports 12 hardware channels which can be configured as inputs and outputs. The functional configuration of the channels is determined by selecting a dedicated mode of operation.

Valve Coupler Mode

In the valve coupler mode, the channels 1, 4, 7, and 10 are used to control 4 low power valves. The channels 2, 3, 5, 6, 8, 9, 11, and 12 are used as valve position feedback inputs for NAMUR proximity switches or mechanical switches. An auxiliary valve is used as a pilot valve for 1 actuator which can be provided with final position feedback contacts to feed back the drive position. In the manual, the term "valve" denotes the overall chain consisting of auxiliary valve, control drive, and regulation unit. Condition monitoring functions like stroke counter, partial stroke test, and travel time survey allow to detect evolving faults, before they become critical for the process control.

The device is designed particularly for intrinsically safe low power auxiliary valves in 6 V design that control the supply of compressed air to the drive. An auxiliary valve of this type is triggered by an intrinsically safe current (I

= 6.4 V ... 7.9 V, IS = 1.5 mA

Refer to the technical data of the MIO for specification of compatible valves and sensors. A list of compatible low power valves and NAMUR sensors are available on the Pepper+Fuchs website.

Binary Input Mode

The device samples the inputs in 2 independent cycles. Channels 1, 4, 7, and 10 are intended to be used for sensing multiplexed binary inputs as vibrating forks, NAMUR sensors, or mechanical switches. Channel 1 can also be configured to be used as a frequency or counter input. If the channel 1 frequency or counter input is activated, channels 4, 7, and 10 are deactivated. The ON-time of channel 1, 4, 7, and 10 can be adjusted individually between 10 ms ... 11 000 ms. The total cycle time is the sum of the 4 individual ON-times.

Channels 2, 3, 5, 6, 8, 9, 11, and 12 are intended to be used for sensing multiplexed binary inputs as NAMUR sensors and mechanical switches. The sampling time of 10 ms is not adjustable. The total cycle time is calculated as follows: number of used channels * 10 ms (minimum 50 ms). If all 8 sensors are used, the total cycle time is 80 ms.

Refer to the technical data of the MIO for the specification of compatible sensors. A list of compatible NAMUR sensors is available on the Pepperl+Fuchs website.

F2* metal housing.

■ The housing has a grounding point with a grounding screw. The grounding connection

must be secured against loosening and corrosion, e. g., by using tinned cable plates.

Note!

Ensure potential equalization of F2 Metal Housings

Ensure that the housing is connected properly to the potential equalization.

Multi-Input/Output Device

Parameterization and Operation

The link between a specific function block and a transducer block is made by channel reference.

4 different types of operation modes are available which are selectable with the resource block parameter MIO_MODE:

Valve Coupler

In the valve coupler mode, 4 discrete output (DO) function blocks and 1 multiple discrete output (MDO) function block can be used individually to establish a FOUNDATION Fieldbus application.

A reference value is specified for the valve position and the current valve position feedback. The reference value for the valve position is transferred to one of the transducer blocks. This transducer block then controls the valve and reads back the current position via the position feedback sensors (PFCs).

In addition, several diagnostic and monitoring functions for the valve can be activated in the transducer blocks.

Binary Input

In the binary input mode, up to 12 discrete inputs are available. 12 discrete input function blocks (DI) and 2 multiple discrete input (MDI) function blocks are available.

For 4 inputs, the sampling time is configurable, for the remaining 8, the sampling rate is fixed.

Diagnostic functions like lead short circuit and breakage can be activated in the transducer blocks.

The position feedback input values can also be transmitted by using individual discrete input function blocks (DI) or multiple input function blocks (MDI).

Frequency Input

In the frequency input mode, 1 frequency input and 8 discrete inputs are available. 1 analog input (AI), 8 discrete inputs (DI), and 1 multiple discrete input (MDI) function block are available.

Diagnostic functions like lead short circuit and breakage can be activated in the transducer blocks.

Counter Input

In the counter input mode, 1 counter input and 8 discrete inputs are available. 1 analog input (AI), 1 discrete output (DO) function block, 8 discrete input (DI) function blocks, and 1 multiple discrete input (MDI) function block are available.

The DO function block allows you to reset the counter value.

The diagnostic function lead breakage can be activated in the transducer blocks.

The following sections are focused on the commissioning of the transducer blocks and their interaction with the function blocks and the resource block. Representation and commissioning of the function blocks and resource block are specific to the control system. Detailed information can be found the documentation of the control system. This document includes a concise list with the explanation of all parameters of the different types of blocks.

4.2 Prerequisites

To parameterize the MIO device, the associated device description (DD) must be included in the engineering tool used. If you require to integrate the MIO device in the control system by yourself, you find the necessary files on the Internet under www.pepperl-fuchs.com.

For detailed information on the import of the device description, refer to the documentation of the the control system in use.

4.3 Device Identification

Each FOUNDATION Fieldbus device has a unique device ID. The device ID is structured as follows for the MIO device:

Manufacturer Idenification Ty p e Serial Number

502B46 = Pepperl+Fuchs

These 3 identification fields are identically structured for all FOUNDATION Fieldbus MIO devices. If several MIO devices are connected to one FF-H1 segment, these devices are differentiated via their individual 14-digit serial numbers. The serial number is also provided on a label attached to the device.

4.4 Commissioning Procedure

The MIO device supports different modes of operation as described. For more information, see chapter 4.1.

Depending on the mode of operation you selected, adhere to the commissioning procedure that applies for this mode.

1. Read manual.

2. Start commissioning.

3. Set mode of operation MIO_MODE (resource block) to either one of the following modes:

1. Valve Coupler

2. Binary Input

3. Frequency Input

4. Counter Input

4. Complete commissioning.

4.5 Parameterization in Valve Coupler Mode

4.5.1 Interaction of Transducer Blocks and DO Function Blocks

In each of the DO function blocks, a reference value is calculated for the valve position in the OUT_D parameter. This value is transferred to the transducer block that is connected with the function block. A function block is connected to a transducer block through the Channel function block parameter. This parameter contains the channel number 1 ... 4 of the transducer block that the function block requires for interaction.

OUT_D of the function block can assume values from 0 ... 255. The value "0" means valve "closed", values  0 mean valve "open".

Note!

Specifics of Reference Value

This specific reference value is contrary to many conventional devices where the value "0" means "valve current OFF" and "1" means "valve current ON".

The transducer block accepts this reference value only if the status is GOOD (C) or GOOD (NC). However, if the status is UNCERTAIN or BAD, the auxiliary valve is not controlled electrically and the drive moves into the mechanical safety position.

If the current valve position is determined by 2 final position feedback sensors, the transducer block transfers the current valve position back to the DO function block. The function block represents the transferred value in the READBACK_D parameter. The numerical value depends on the parameterization of the transducer block.

Additional Diagnostic Information

In addition to the reference value for the valve position and the current valve position, also diagnostic information is transferred between the function block and the transducer block. Thus, it is possible to receive diagnostic messages from the transducer block also with control systems which do not support alarms of transducer blocks.

For more information, see chapter 4.5.12.

Primary Value Parameter - Inversion and Behavior in Cyclic Transfer

The READBACK_D parameter is shown with the Primary Value parameter within the DO function block. If the IO option "invert" is activated in the function block, the numerical value is inverted. That means, a value of "0" becomes "1", a value  0 becomes "0".

If the current valve position is to be cyclically transferred to a control system or used in a function block application, the value of the Primary Value parameter can be transferred to BKCAL_OUT_D via the IO option "PV for BKCal_Out". If this option is not activated, the value of BKCAL_OUT_D is only a copy of the current reference value.

4.5.2 Valve/Actuator Design

This section explains the setting options for the behavior of the valve or actuator with the Act. Fail Action parameter, i.e., the actuator fail action.

Note that for setting this parameter, the target mode of the transducer block must be set to "Out of Service" (OOS).

2017-06

Multi-Input/Output Device

Parameterization and Operation

Actuator Drive Design with Act. Fail Action Parameter

The MIO device supports the 2 most frequent valve drive designs "self-opening" and "selfclosing". For choosing between these 2 options, the actuator drive and the control actuators must be considered a unit. Self-opening and self-closing designate the behavior of the drive when setting the electrical control system to "0". This is independent of the behavior of the drive during a failure of the auxiliary power. The following values can be set:

■ Undefined

■ Self-opening

■ Self-closing

The value "undefined" is the default setting at the time of delivery. Setting the valve drive to a defined state is required for the configuration of the MIO device. The transducer block leaves the mode "Out of Service" only if 1 of the 2 options "self-opening" or "self-closing" is set.

Depending on the setting of the Act. Fail Action parameter, the transducer block determines whether or not the connected auxiliary valve must be controlled electrically for starting a position set by the function block.

Controlling a double-acting drive requires 2 channels, i. e., 2 DO function blocks and 2 transducer blocks.

4.5.3 Final Position Feedback

This section describes the options for parameterizing the final position feedback contact.

Prerequisite: Ensure that the Act. Fail Action parameter has a value assigned for the design of the valve drive.

The response of the final position feedback contact is influenced by the following 2 parameters:

■ Sensor Usage parameter: Describes whether a final position feedback contact is

connected to the MIO device and how to evaluate its signals.

■ PV_D Generation parameter: If the signals of the final position feedback contacts are

evaluated, this parameter determines how to further process the evaluated signals prior to transferring them to the function block.

Sensor Usage Parameter

The following settings are possible:

■ No position detection

■ Use sensor values for the Primary Value

■ Use options A ... D to determine the Sensor Usage parameter

No position detection

No final position feedback contact is connected to the MIO device. The current reference value is returned as valve position to the function block.

Use sensor values for the Primary Value parameter

The 2 signals of the final position feedback contacts are transferred to the function block without evaluation. The 2 binary signals are represented on bit 0 (position feedback contact A) and bit 1 (position feedback contact B). Here, numerical values can be generated from 0 ... 3. Possible problems are described in the next section PV_D Generation parameter.

Observe that the MIO device interprets a final position feedback contact signal as follows:

High current => logical 1

Low current => logical 0

2017-06

Multi-Input/Output Device

Parameterization and Operation

A ... D Sensor Usage

When selecting one of the options A ... D, the transducer block determines from the position feedback contact signals the position of the valve as "open", "closed", "intermediate" at that moment. Whether an actuated sensor or activated mechanical contact represents an open or a closed valve, depends on the design of the position feedback and the electrical characteristics of the final position feedback contacts. A general representation is thus not possible.

Each of the 4 options corresponds to 1 set of combinations of the 2 final position feedback contacts signals and the valve positions "open", "intermediate", and "closed". The following 4 tables show the signal combinations of final position feedback contact A and final position feedback contact B assigned to a valve position for the options A ... D.

The letter/number combinations after the options A ... D denote the signal input for the positions:

■ O: open

■ I: intermediate

The following table gives the assignment of the position feedback contact signals "0" and "1" to the numerical values 0 ... 3:

1 1 0

2 0 1

3 1 1

PV_D Generation Parameter

If you selected one option from A ... D for the Sensor Usage parameter, you can use the PV_D Generation parameter to determine what to do with the evaluated signals prior to transferring them to the function block. You can select one of the following options:

■ Val ve position

■ Valve position extended

■ Intermediate => Closed

■ Intermediate => Open

■ Intermediate => Next

■ Intermediate => Last (default)

Valve Position

The position of the valve is transferred to the function block as a numerical value:

Numerical Value Valve Pos ition

1 Closed

2 Open

3 Intermediate position

0 Unkown

2017-06

Multi-Input/Output Device

Parameterization and Operation

Valve Position Extended

In the intermediate position of the valve, the information on the valve position is extended with the information "opening" and "closing". This information is determined by the current control process and need not coincide with the actual direction of travel (e. g., when changing the set position while the valve is in the intermediate position).

Numerical Value Valve Po sition

1 Closed

2 Open

3 Intermediate position/opening

4 Intermediate position/closing

0 Unkown

The options "Valve Position" and "Valve Position Extended", and the setting "Use sensor values for PV_D" in the Sensor Usage parameter are intricate to be used with the function block.

The transducer block transfers the valve position to the function block as part of the READBACK_D parameter. From there, the valve position information is transferred to the Primary Value parameter which can be cyclically transferred to a control system via BKCAL_OUT_D. Alternatively, the valve position information can be used in a function block application.

If an inversion is active in the function block, the numerical value "0" becomes "1" and all numerical values  0 become "0". That means, all valid valve positions are inverted to "0".

Also, the IO options of the DO function block "SP-PV Track in LO" and "SP-PV Track in Man" do no longer work because the range of values of the Primary Value parameter does not correspond to that of SP_D.

In order to ensure a more straightforward use of the valve position information in the function block, you can choose one of the following options.

These options show the valve position at the value range of the set position "closed" (0) or "open" (1) and determine the position information to be issued in the intermediate position:

■ Intermediate => Closed: The intermediate position is always interpreted as "closed"

■ Intermediate => Open: The intermediate position is always interpreted as "open"

■ Intermediate => Next: During a closing process, the intermediate position is always

interpreted as "closed" and during an opening process as "open"

■ Intermediate => Last (default setting): During a closing process, the intermediate

position is interpreted as "open" and during an opening process as "closed"

The default setting "Intermediate => Last" has the effect that during an opening or closing process, the last position is displayed until the valve has actually reached the reference position. This is useful, e. g., for a sequential valve control when any further steps can only take place after the valve has fully reached the desired position. In this case, only the reference value must be compared with the feedback.

4.5.4 Target Mode

The "Target mode" determines the mode of operation of the MIO device. The modes of operation are possible:

■ Out of service (OOS, default setting)

■ Auto

■ Manual (Man)

2017-06

Multi-Input/Output Device

Parameterization and Operation

In OOS mode, the transducer block is deactivated and the valve output is not controlled. Thus, a connected actuator drive moves in its mechanical safety position. Use this mode if you intend to adjust basic function parameters, e. g., Act. Fail Action, Sensor Usage, and PV_D Generation or if the corresponding channel is not used.

The "Auto" mode is provided for operation. The transducer block operates in this mode as specified by parameterization.

"Man" is used by the setup wizard and must not be modified.

4.5.5 Time Monitoring

The MIO device can monitor the breakaway and transit times of a valve. You can activate the time monitoring parameter to measure the breakaway and transit times of the connected valve. You can compare the measured values to the reference values during each reference value modification of the valve position.

If a measured time is longer or shorter than the reference time plus a specified tolerance, an alarm is generated. The times measured last are also displayed.

Prerequisites

The following parameters must be set as a prerequisite for time monitoring:

■ Act. Fail Action. For more information, see chapter 4.5.2.

■ Sensor Usage. For more information, see chapter 4.5.3.

Activation of Time Monitoring

You can activate time monitoring by setting the option Time Monitoring in the Valve Monitoring parameter.

4.5.6 Cyclic Function Test (Partial Stroke Test)

Prerequisites

The following parameters must be set as a prerequisite for the cyclic function test:

■ Act. Fail Action parameter. For more information, see chapter 4.5.2.

■ Sensor Usage parameter. For more information, see chapter 4.5.3.

■ Valve Monitoring parameter > Time Monitoring is activated. For more information, see

chapter 4.5.5.

"Cyclic Test Open" and "Cyclic Test Closed"

The MIO device provides a function check for the connected valve or actuator within an adjustable period of time. This way, you can monitor valves or actuator that are rarely triggered for faults. When active, the MIO device controls the valve or actuator contrary to the current control until the breakaway point. Then, the MIO device controls the valve or actuator back into the initial position.

The measured breakaway time is displayed as the last breakaway time measured, and falling below or exceeding the admissible range of values generates an alarm.

Depending on the operation, the cyclic function test for the valve position "open" or "closed" can be switched ON or OFF under the Valve Monitoring parameter.

Note that the time monitoring option must be activated in Valve Monitoring in order to use the cyclic function test.

"Period Cyclic Test"

You can set a time interval for the cyclic function test. The interval can range between 10 seconds and 7 days, 23 hours, 59 minutes and 59 seconds. If the set valve position is not modified after this time, the device automatically carries out a cyclic function test.

4.5.7 Stroke Counter

The MIO device can monitor the number of strokes of a valve.

In the Valve Monitoring parameter, use the Stroke Counter to activate this function.

A stroke starts in the valve status "open" and continues with a closing and opening procedure. When activated, the Stroke Counter increases by 1, after the valve is closed and opened again.

This parameter can be initialized with a start value. The current count remains unaffected even after a voltage failure.

Stroke Counter Limit

You can determine a count as the limit value for the counter function. If the count of the Stroke

Counter exceeds the stroke counter limit entered, the alarm "Maintenance needed now“ is

generated. No alarm is given if the stroke counter limit is 0. This way, you can count the number of strokes without releasing an alarm for a limit value.

Parameterization and Operation

4.5.10 Final Value as Valve Reference Value

The reference value for the valve position and the associated status are issued in the Final Value parameter. The Final Value is a copy of the OUT_D value of the DO function block connected with the transducer block. This reference value can assume the values "closed" (0) or "open" ( 0).

The value is accepted only with a status GOOD-NonCascade or GOOD-Cascade. If the status is BAD or UNCERTAIN, the connected auxiliary valve is not controlled electrically, so that the associated drive moves into the mechanical safety position.

4.5.11 Valve Position

The signals recorded by a connected final position feedback contact are indicated in several parameters of different significance.

Sensor Value A or Sensor Value B Parameter

These parameters display the input signal of final position feedback contact A or final position feedback contact B. The MIO device interprets a final position feedback contact signal as follows:  high current => logical 1  low current => logical 0

Valve Posi tion Parameter

The current valve position "open", "intermediate", or "closed" is displayed as value. By setting the Sensor Usage parameter accordingly, the signals of the final position feedback contacts are assigned a definite position.

For more information, see chapter 4.5.3.

Valve Position Extended Parameter

In the intermediate valve position, the information in the valve position parameter is extended by the information "opening" and "closing". This information is determined by the current control process and need not coincide with the actual direction of travel - i. e., when changing the set position while the valve is in the intermediate position.

Primary Value Parameter

This parameter issues the value which is fed back as valve position to the assigned function block. The Primary Value parameter is an unsigned 8 with the status which is displayed in the function block as READBACK_D. Which information is issued at which value range in the Primary Value parameter depends on how you set the Sensor Usage and PV_D Generation parameters.

For more information, see chapter 4.5.3.

Valve Info Parameter

This parameter displays information of the current status of the valve or transducer block. This includes the following information:

■ Stroke counter limit exceeded

■ Cyclic function test running

■ Actuation - The valve has not yet reached the new final position after having changed the

reference value.

4.5.12 Diagnostic Messages and Alarms

The MIO device features several diagnostic options.

If a fault occurs, the transducer block sets a block alarm. The block alarm is a combined error signal for all fault signals and remains set, as long as a fault in the block exists. For detailed information of the alarm cause after a block alarm, the MIO device provides the following parameters:

■ Block Err.

■ XD Error

■ Valve Lead Fault

■ Sensor Lead Fault

■ Valve Warning

■ Valve Error

■ Val ve Info

If the control system in use supports alarm messages via the FOUNDATION Fieldbus, setting and resetting of the block alarm is transferred via the bus to the control system. As this function is currently not supported by all control systems, the MIO device offers an alternative option to issue faults:

As soon as the transducer block recognizes a fault, a message is set in Block Err. parameter of the connected DO function block. Normally, this parameter is read out and evaluated in cycles by control systems which do not support alarm messages via FOUNDATION Fieldbus.

If the fault is related to the valve control (e. g., lead breakage of valve feeding lead or exceeding the admitted valve transit time), the message "Output failure" is set. If the final position feedback contact fails (e. g., lead short circuit of the lead that feeds the final position feedback contact), the message is "Input failure".

All messages, except a configuration error, are transferred this way. Therefore, check after each modification of parameterization of the MIO device that this message is not set in the Block Err. parameter. If the control system used does not support alarm messages via FOUNDATION Fieldbus, in the Features Sel. resource block parameter, deactivate the option "Reports".

More Information

For more information on diagnostic options and troubleshooting, see chapter 5. For a detailed list of the messages of the tranduceer block parameters and for troubleshooting, see chapter 5.4.

4.6 Parameterization in Binary Input Mode

The binary mode supports up to 12 discrete inputs, organized in the following 2 groups:

■ Group 1: Hardware channels 1, 4, 7, 10

■ Group 2: Hardware channels 2, 3, 5, 6, 11, 12

The device samples the inputs in 2 independent cycles. Group 1 hardware channels 1, 4, 7, 10 are intended to be used for sensing multiplexed binary inputs as vibration forks, NAMUR sensors, or mechanical switches. The ON-time of group 1 channels can be adjusted individually in a range between 10 ms ... 11 000 ms. The total cycle time is the sum of the 4 individual ON-times.

Group 2 hardware channels 2, 3, 5, 6, 11, 12 are intended to be used for sensing multiplexed binary inputs as NAMUR sensors and mechanical switches. The sampling time is fixed to 10 ms and is not adjustable. The total cycle time is the product of the number of channels used x 10 ms. The minimum total cycle time is 50 ms. If all 8 sensors are used, the total cycle time is 80 ms.

4.6.1 Transducer Blocks Interacting with DI or MDI Function Blocks

For the discrete inputs, the hardware channels can be linked to function blocks in different ways.

Using 12 Individual DI Function Blocks

Each discrete input is linked to the independent DI function blocks 5 … 17. For group 1 hardware inputs, the transducer block channels 301 … 304 are used. For group 2 hardware inputs, the channels 201 … 208 are used.

Group 2 hardware inputs are linked to an MDI using channel number 200.

1 300 1,4,7,10

2 200 2,3,5,6,8,9,11,12

Using 2 DI Function Blocks

If required, you can use this option to increase the update time performance. Use the sensor inputs with 2 DI function blocks to read the input states of the 2 hardware input groups.

Group 1 sensor inputs are linked to a DI by using channel number 305.

Group 2 sensor inputs are linked to a DI using channel number 5.

The input values are assigned to the respective bits of the FIELD_VAL_D parameter value of the transducer blocks according to the following tables:

Group 1 Hardware Inputs

4 Sensor value hardware channel 8

5 Sensor value hardware channel 9

6 Sensor value hardware channel 11

7 Sensor value hardware channel 12

In the DI function block, the value of the FIELD_VAL_D parameter is assigned to the Primary Value parameter, and from there, to the OUT_D parameter value. Thus, cyclic transmission of the groups of sensor values to a control system is possible as well as their further use in a function block application.

Because of the many inputs mapped to a single parameter, the status does not reflect the status of a specific input any more. Failures, such as lead breakage or lead short circuit of the sensor wires are no longer issued using the status. The status remains GOOD in all instances.

Only hardware failures of the MIO device are issued with the status BAD - Device Failure.

With the PV_FTIME parameter, you can determine for how long (in seconds) the final position feedback sensor values have to be stable, before they are passed on from the FIELD_VSL_D parameter to the Primary Value parameter.

Depending on the application used, sensor values can keep changing or influencing one another. In this case, an inappropriate numeric value can result in the Primary Value parameter not being updated at all. Therefore, Pepperl+Fuchs recommends setting the PV_FTIME parameter to 0. If time monitoring is not necessary, Pepperl+Fuchs recommends setting the Sensor Usage parameter to "Use sensor values for PV_D".

4.6.2 Enabling/Disabling Hardware Channels 1, 4, 7, 10

Use the Sensor Exe Mode parameter to individually enable or disable the channels 1, 4, 7, 10. The Sensor On-Time parameter defines the time a specific hardware input is powered and processed before the next hardware input is switched on.
