  • Page 7: Introduction

    Introduction This chapter provides an introduction to automation with Advant Controller 31 (AC31), from the overall architecture to the operational rules of the 40 and 50 series basic units. General information on the AC31 system The AC31 system comprises the 40, 50 and 90 series. This operating guide describes the 40 and 50 series.
  • Page 8: General Setup Rules

    General setup rules An AC31 system always includes an AC31 basic unit. There are three types of basic units: - The 40 series basic units with a local inputs/outputs extensions interface. - The 50 series basic units with a local inputs/outputs extensions interface and a CS31 bus in- terface for remote extensions.
  • Page 9: Basic Units With Remote Extensions Option

    - 30 and 90 series remote units (without central extension capacities) with analog/digital in- puts/outputs - High-speed counter units - ABB frequency converter - Air pressure actuators - 50 series basic units - 90 series basic units as slaves with their own user programs - or any other devices which support CS31 communication (see Figure 2).
  • Page 10: Operation Of The 40 And 50 Series Basic Units

    Operation of the 40 and 50 series basic units 1.3.1 Functional diagram The memory of the 40 and 50 series is composed of two distinct areas: - A RAM memory where the user program and data is loaded - A Flash EPROM memory which contains: - a backup of the user program with the program constants, - the configuration data - and the system program, which is protected against access by the user program.
  • Page 11: Program Execution

    1.3.2 Program execution The basic unit microprocessor ensures the cyclic execution of the user program as shown in Figure 4. The internal processing: - PLC monitoring and control - operating and test functions is executed in parallel with the previously described cycle. The execution duration of a cycle (bus cycle + program cycle) is controlled by the basic unit.
  • Page 12: Bus Transmission

    1.3.3 Bus transmission The master basic unit manages the transmission of messages to the various slaves via the RS485 connection. The messages are transmitted in the following format: - Request from the master basic unit: address data CRC8 - Request from the remote units: start data CRC8...
  • Page 13: Refresh Times/Response Times

    1.3.4 Refresh times/response times Bus refresh times and basic unit response times depend on the system configuration, the number and type of the remote units on the CS31 bus. Bus refresh times The bus refresh times correspond to the transmission time over the bus. The calculation corre- sponds to the addition of all the communication times of the remote units on the bus and the base time of the master basic unit.

    • Never short-circuit the battery! There is danger of overheating and explosion. Avoid acci- dental short-circuits, therefore do not store batteries in metallic containers or boxes and do not bring them into contact with metallic surfaces. • Replace the battery only whith the supply voltage on! Otherwise you risk data being lost.

    Addressing 4.5.1 Input/output variables Addressing the CS31 bus enables the user to program the utilization of the inputs/outputs in a manner that is completely transparent to the user. The inputs/outputs of a AC31 remote unit are defined by: - their type (input or output, digital or analog), - the unit address, - the channel number on the unit.
  • Page 67 • Master or stand-alone basic unit The address 62 is automatically assigned to the inputs/outputs of a basic unit. Their addresses are assigned automatically according to the order of the extensions: - The first digital inputs extension is assigned the address 63, and the subsequent extensions are incremented by 1, up to 68.
  • Page 68: Addressing Slave Basic Units Or Remote Extension Units On The Cs31 Systembus

    A remote unit may be: - a non-extensible remote unit - an extensible remote unit with digital extensions - an ABB variable speed drive via NCSA-01 - a high-speed counter - a basic unit (50 series with extension capabilities, 90 or 30 series) Warning: An extensible remote unit ICMK 14xx with analog extensions occupies two addresses.
  • Page 69 Addressing rule: - The first digital input extension is assigned the address X+1. The following extension is incremented by 1 and so on until 61. CS 31 EW / EW / series interface master Addresses Remote unit Addresses X+2 X+3 - The first digital input extension is assigned the address X+1.
  • Page 70 When an analog extension unit is present amongst the extensions, the unit is assigned the same address value as that of the extensible remote unit to which it is connected. Address values = ( 0 ≤ X ≤ 61 ) If an analog XM 06 B5 type extension unit is used, it is possible to connect a maximum of two units to the extensible remote unit, because the number of inputs and outputs of this unit is less than eight.
