Chapter 1 About this document Introduction This document describes Access controller application communication possibilites in terms of integration as communication slave via EXOline, Modbus and BACnet. Software version Access version Available V4.0-1-04 Modbus are available V4.0-1-05 EXOline, BACnet and Modbus are available later NaviPad 1.1.0.
Supported Modbus functions: 1 = Read Coils 2 = Read Discrete Input 3 = Read Holding Register 4 = Read Input Register 5 = Write Single Coil 6 = Write Single Register 15 = Write Multiple Coils 16 = Write Multiple Registers BACnet type The BACnet type of signals: 10XXX = Read and write binary 20XXX = Read binary 30XXX = Read and write analogue 40XXX = Read analogue 30XXX = Read and write multistate 40XXX = Read multistate (Where XXX = Modbus address) NOTE: In the variable lists contained in this manual, the
Chapter 2 System integration Modbus Addresses All addresses starts with 0, and due to that some Master devices starts address with 1 (equal to register) it’s in that case necessary to add all addresses in this document with +1. Communication limitations The Modbus master must wait for a minimum of 3.5 character times (4 ms at 9600 bps) between two messages.
When using Modbus TCP the controller Ethernet port in combination with TCP port setting 502 should be used. Writing values To override the output values, set the output to manual mode using a Modbus signal. Then set the corresponding ..._ManSet signal to the wanted level. These signals are listed in Chapter 5: Holding Registers. Remember that only values with a default value are adjustable, you will find these in the chapters Coil Status Register and Holding Register.
BACnet Access from software version 4.0-1-05 is capable of communication via the BACnet-ASC (Application Specific Controller) protocol and from 4.3-1-00 with BACnet AAC (Advanced Application Controller). In order to connect a Access application to a BMS (Building Management System) via BACnet/IP use the TCP/IP port. BACnet/IP configuration (Activation status of BACnet/IP protocol) Upon delivery, the BACnet/IP protocol is disabled as a default.
DHCP The Dynamic Host Configuration Protocol (DHCP) is a network protocol used on Internet Protocol (IP) networks for dynamic distribution of network configuration parameters, such as IP addresses, DNS servers and other services. The Access controller can be configured to either obtain an IP address from a DHCP server (dynamic) or the address can be set manually (static).
Watchdog Access from software version 4.1-1-00 is capable of supervising communication recieved from a BMS master. One slave communication protocol can be monitored at a time. If no active communication from the BMS master is detected before the watchdog timeout elapses, an alarm message is generated. BMS watchdog (Activation of protocol) Upon delivery, the BMS watchdog is disabled as default.
Ethernet setting When NaviPad and Control unit are connected directly to each other via switch module without any DHCP server they assign themselves with Auto-IP (Link-local) addresses and then randomly pick from address range 169.254.x.y (255.255.0.0). The possibility of using a static IP address as alternative to a dynamic IP address (DHCP) is available from Access software version 4.0-1-04 and NaviPad software version 1.1.0.184.

Tables of variables with register addresses Tables with communication variables and register addresses from document version (A010) are available as printout, see APPENDIX, and as a MS Excel file attached to this PDF. To access the attached Excel workbook, this document has to be opened with a dedicated PDF reader application (e.g. free version of Adobe Reader).
