1: AS-INTERFACE

Introduction

This chapter describes general information about the Actuator-Sensor-Interface, abbreviated AS-Interface.
AS-Interface is a type of field bus that is primarily intended to be used to control sensors and actuators. AS-Interface is a

network system that is compatible with the IEC62026 standard and is not proprietary to any one manufacturer. A master
device can communicate with slave devices such as sensors, actuators, and remote I/Os, using digital and analog signals
transmitted over the AS-Interface bus.

The AS-Interface system is comprised of the following three major components:

• One master, such as the MicroSmart AS-Interface master module (FC4A-AS62M)

• One or more slave devices, such as sensors, actuators, switches, and indicators

• Dedicated 30V DC AS-Interface power supply (26.5 to 31.6V DC)

These components are connected using a two-core cable for both data transmission and AS-Interface power supply. AS­Interface employs a simple yet efficient wiring system and features automatic slave address assignment function, while
installation and maintenance are also very easy.

Applicable Sensors and Actuators for AS-Interface

AS-Interface Compatible Sensors and Actuators

AS-Interface compatible sensors and actuators communicate using the built-in AS-Interface function, and serve as AS­Interface slaves when connected directly to the AS-Interface bus via a branch unit or a T-junction unit.

Sensors/Actuators Not Compatible with AS-Interface

Conventional sensors and actuators that are not compatible with the AS-Interface can also be connected to the AS-Inter­face bus using a remote I/O slave and be handled in the same way as devices that are compatible with the AS-Interface.

AS-Interface System Requirements

Master

The AS-Interface master controls and monitors the status of slave devices connected to the AS-Interface bus.
Normally, the AS-Interface master is connected to a PLC (sometimes called ‘host’) or a gateway. For example, the

AS-Interface master module is connected to the MicroSmart CPU module.

Slaves

Various types of slave devices can be connected to the AS-Interface bus, including sensors, actuators, and remote I/O
devices. Analog slaves can also be connected to process analog data.

Slaves are available in standard slaves and A/B slaves. Standard slaves have an address of 1 trough 31 in the standard
address range. A/B slaves have an address of 1A through 31A in the standard address range or 1B through 31B in the
expanded address range. Among the A/B slaves, slaves with an address of 1A through 31A are called A slaves, and slaves
with an address of 1B through 31B are called B slaves.

AS-Interface Power Supply

The AS-Interface bus uses a dedicated 30V DC power supply (AS-Interface power
supply), which is indicated with the AS-Interface mark. General-purpose power sup­ply units cannot be used for the AS-Interface bus.

Caution

• Use a VLSV (very low safety voltage) to power the AS-Interface bus.
The normal output voltage of the AS-Interf ace po wer supply is 30V DC.

AS-Interface Marks

Cables

The AS-Interface bus uses only one cable to transmit signals and power. Use one of the following cable types (the wire
does not have to be stranded).

• Standard yellow unshielded AS-Interface cable (with polarity)

• Ordinary two-wire flat cable

1: AS-INTERFACE

Main Features of AS-Interface V2 with Slave Expansion Capability

The AS-Interface is a reliable bus management system in which one master periodically monitors each slave device con­nected on the AS-Interface b us in sequence. The master manages the I/O data, parameters, and identification codes of each
slave in addition to slave addresses. The management data depends on the type of the slave as follows:

Standard Slaves

• A maximum of four inputs and four outputs for each slave

• Four parameters for setting a slave’s operation mode (P3, P2, P1, P0)

• Four identification codes (ID code, I/O code, ID2 code, and ID1 code)

A/B Slaves

• A maximum of four inputs and three outputs for each slave

• Three parameters for setting a slave’s operation mode (P2, P1, P0)

• Four identification codes (ID code, I/O code, ID2 code, and ID1 code)

Note 1: Parameters P3 through P0 are used to set an operation mode of the slave. For details, see the user’s manual for
the slave.

Note 2: The slaves connected to the AS-Interface bus are distinguished from each other by the ID code and I/O code con­tained in each slave. Some slaves have ID2 code and ID1 code to indicate the internal functions of the slave. For example,
analog slaves use the ID2 code to represent the channel number of the slave.

Note 3: The MicroSmart AS-Interface master module is also compatible with AS-Interface ver. 2.1 and earlier slaves.

Slave Addresses

Each standard slave connected to the AS-Interface bus can be allocated an address of 1 through 31. Each A/B slave can be
allocated an address of 1A through 31A or 1B through 31B. All sla ves are set to address 0 at factory before shipment. The
address of a slave can be changed using the “addressing tool.” Using WindLDR, the addresses of slaves connected to the
AS-Interface master module can be changed (see page 7-1).

When a slave fails during operation and needs to be replaced, if the auto addressing function is enabled on the master mod­ule, just replace the slave with a new one (with address 0 and the same identification codes). The new slave will automati­cally be allocated the same address as the slave that was remov ed, and you do not ha v e to set the address again. F or details
of the ASI command to enable auto addressing, see page 6-17.

Slave Identification

Slaves have the following four identification codes. The master checks the identification codes to determine the type and
feature of the slave connected on the AS-Interface bus.

ID Code

The ID code consists of 4 bits to indicate the type of the slave, such as sensor, actuator, standard slave, or A/B slave. For
example, the ID code for a standard remote I/O is 0, and that for an A/B slave is A (hex).

I/O Code

The I/O code consists of 4 bits to indicate the quantity and allocation of I/O points on a slave.

I/O Code Allocation I/O Code Allocation I/O Code Allocation I/O Code Allocation

0h I, I, I, I 4h I, I, B, B 8h O, O, O, O Ch O, O, B, B

1h I, I, I, O 5h I, O, O, O 9h O, O, O, I Dh O, I, I, I

2h I, I, I, B 6h I, B, B, B Ah O, O, O, B Eh O, B, B, B

3h I, I, O, O 7h B, B, B, B Bh O, O, I, I Fh (reser ved)

I: input, O: output, B: input and output

ID2 Code

The ID2 code consists of 4 bits to indicate the internal function of the slave.

ID1 Code

The ID1 code consists of 4 bits to indicate additional identification of the slave. Standard slaves can have an ID1 code of
0000 through 1111 (bin). A/B sla ves use the MSB to indicate A or B slave, and can have a unique value only for the lower
three bits. The MSB of A slaves is set to 0, and that of B slaves is set to 1.

MICROSMART AS-INTERFACE MASTER MODULE USER’S MANUAL 1-3

1: AS-INTERFACE

Quantities of Slaves and I/O Points

The quantity of slaves that can be connected to one AS-Interface bus is as follows.

• Standard slaves: 31 maximum

• A/B slaves: 62 maximum

The limits for slave quantities given above apply when the slaves are either all standard slaves or are all A/B slaves.
When 62 A/B sla v es (with four inputs and three outputs) are connected, a maximum of 434 I/O points (248 inputs and 186

outputs) can be controlled over the bus.
When using a mix of standard slaves and A/B slaves together, the standard slaves can only use addresses 1(A) through

31(A). Also, when a standard slave takes a certain address, the B address of the same number cannot be used for A/B
slaves.

AS-Interface Bus Topology and Maximum Length

The AS-Interface bus topology is flexible, and you can wire the bus freely according to your requirements.
When repeaters or extenders are not used, the bus length can be 100m (328 feet) at the maximum.

AS-Interface Bus Cycle Time

The AS-Interface bus cycle time is the amount of time required for a master to cycle through every slave on the bus.
The information for each slave is continuously transmitted over the bus in sequence, so the AS-Interface bus cycle time

depends on the quantity of active slaves.

• When up to 19 slaves are active, the bus cycle time is 3 msec.

• When 20 to 31 slaves are active, the bus cycle time is 0.156 × (1+N) msec where N is the number of slaves.

When A slave and B slave have the same address number (e.g. 12A and 12B), the two slaves are alternately updated each
cycle. Therefore, when the system consists of 31 A slaves and 31 B sla v es, then the AS-Interface b us c ycle time will be 10
msec.

Maximum AS-Interface Bus Cycle Time

• When 31 slaves are connected, the maximum bus cycle time is 5 msec.

• When 62 slaves are connected, the maximum bus cycle time is 10 msec.

High Reliability and Security

The AS-Interface employs a transfer process of high reliability and high security. The master monitors the AS-Interface
power supply voltage and data transmitted on the bus, and detects slave failures and data errors.

Even when a slave is replaced or a new slave is added during operation, the AS-Interface master module need not be shut
down and can continue uninterrupted communication with other active slaves on the bus.

Introduction

This chapter describes specifications of the MicroSmart AS-Interface master module and applicable cables.

AS-Interface Master Module Type Number

Module Name Type No.

AS-Interface Master Module FC4A-AS62M

The AS-Interface master module can connect a maximum of 62 digital I/O slaves. A maximum of seven analog I/O sla ves
can also be connected to the AS-Interface master module (compliant with AS-Interface ver. 2.1 and analog slave profile

7.3).
The AS-Interface master module can be used with the 20-I/O relay output slim type CPU modules (FC4A-D20RK1 and

FC4A-D20RS1) and the 40-I/O slim type CPU modules (FC4A-D40K3 and FC4A-D40S3). Use a CPU module version of
201 or higher. When using WindLDR, use ver. 4.21 or higher.

Caution

• The AS-Interface master module cannot be used with the all-in-one type CPU modules and the
20-I/O transistor output slim type CPU modules.

• Only one AS-Interface master module can be connected to the slim type CPU module. If more
than one AS-Interface master module is connected, an error occurs and special data register
D8037 (quantity of expansion I/O modules) stores error code 40 (hex).

• Normally, a maximum of seven expansion I/O modules can be connected to the slim type CPU
module. But when the AS-Interface master module is connected, only a total of six expansion
modules can be connected, including the AS-Interface master module. Do not connect more than
six expansion modules due to the amount of heat generated. If more than six expansion modules,
including the AS-Interface master module, are connected, an error occurs and special data regis­ter D8037 (quantity of expansion I/O modules) stores error code 20 (hex).

• The AS-Interface master module can connect a maximum of se v en analog I/O sla ves. When more
than seven analog I/O slaves are connected, the AS-Interface system will not operate correctly.

Assembling Modules

Caution

The following example demonstrates the procedure for assembling the 40-I/O type CPU module and the AS-Interface
master module together. When assembling the 20-I/O relay output type CPU module, take the same procedure.

1. When assembling an AS-Interface master mod-

ule, remove the expansion connector seal from
the 40-I/O type CPU module.

2. Place the CPU module and AS-Interface master module

side by side. Put the expansion connectors together for easy
alignment.

• Assemble MicroSmart modules together before mounting the modules onto a DIN rail. Attempt
to assemble modules on a DIN rail may cause damage to the modules.

• Turn off the power to the MicroSmart before assembling the modules. Failure to turn power off
may cause electrical shocks.

3. With the expansion connectors aligned correctly and the

blue unlatch button in the down position, press the CPU
module and AS-Interface master module together until the
latches click to attach the modules together firmly. If the
unlatch button is in the up position, push down the button to
engage the latches.

Note: When assembling other I/O modules with the AS-Interface
master module, take the same procedure.

Disassembling Modules

Caution

1. If the modules are mounted on a DIN rail, first remove the

modules from the DIN rail as described on page 3-3.

2. Push up the blue unlatch button to disengage the latches,

and pull the modules apart as shown.

Note: When disassembling other I/O modules from the AS-Inter­face master module, take the same procedure.

• Remove the MicroSmart modules from the DIN rail before disassembling the modules. Attempt
to disassemble modules on a DIN rail may cause damage to the modules.

• Turn off the power to the MicroSmart before disassembling the modules. Failure to turn power
off may cause electrical shocks.
