Woodley Protokol interface AK-PI 100

ADAP-KOOL® Refrigeration control systems

Introduction Function The AK-PI 100 is an intermediary link allowing Woodley type units to be operated by an AK-SC 255 system controller. This way of operating the Woodley units replaces the previous Woodley S5 operating interface.

Application The AK-PI 100 is used on systems with an AK-SC 255 system controller, but which still contain older Woodley type units. These types can be: • Woodley MDM units • Woodley 4 way TPI cards • Older units connected to the WTP bus (WTP = Woodley Third Party) Measurements and status readings from the individual Woodley units are uploaded to the AK-PI 100 and on to the AK-SC 255, where the data is presented in the same way as other ADAPKOOL(r) units.

Principle The AK-SC 255 and the AK-PI 100 are linked by Ethernet. For a straightforward connection, the two units can be linked by a switch. In this case, the IP addresses are set to static addresses. You can choose any addresses, but only if nothing else is connected. (It is easiest to use a router and dynamic address allocation. In this case, the router allocates one address to the AK-SC 255 and another to the PI unit. You can only use this solution if the system is self-contained with no contact to an external operating interface.) In larger systems or if IP communication takes place from the system, the connection must be based on a router or a switch. If a router is used, the IP address of the AK-PI 100 may be dynamic, but the address of the AK-SC 255 must be static. If a switch is used, both must be static. You will need to request static addresses from the IT department yourself, and then configure the addresses in both units. You should always use this solution if the system is accessed by an external service company, for example for log extraction, alarm handling or servicing.

AK-PI 100

Communication/number of addresses An AK-PI 100 can be configured for two types of communication - MDM communication or WTP communication. If both types of communication are needed in the system, two AK-PI 100 units must be used. With MDM communication, up to 160 controllers can be connected to one AK-PI 100. With WTP communication, up to 128 controllers can be connected to one AK-PI 100. In total, the AK-SC 255 can handle up to 162 addresses, including units connected directly to the system controller. Addresses In principle, there are three types of address: IP addresses An IP address must be configured for the system controller and for the AK-PI 100. The address can be either static or dynamic - the choice is made by changing a setting. To use a static address, you also need to configure the address. If the system is accessed from the outside, the system controller should always be set to static, so that the external connection always knows the address and is able to contact the unit. (The IP is configured using a menu.) Network addresses A network must always have one, and only one, unit acting as master. In this case, the master is AK-SC 255. To specify this, the address is configured to = 0. This master controls communication with all other controllers in the network. A PI unit is handled as a controller in the network, and you can view its address in the “Channel PI-100/200” screen. Each PI unit is configured with a different address. You can choose 11, 12 or above, e.g. 21. (Addresses 1 to 10 are reserved for subnets.) Connection: When you configure the system controller, the relevant AK-PI 100 is assigned to the network. The system controller then recognises the link to all the MDM units/WTP units. The check marks in the screenshot on the right show that contact with PI units has been selected. One has the address 21 and the other has the address 90 (the numbers 084Z8521 and 22 indicate that there is one PI 200 and one PI 100). Controller addresses All controllers in the same network must have different addresses. This means all controllers connected to a system controller via: • LON communication • MOD bus communication • DANBUSS communication via an AK-PI 200 • MDM communication via an AK-PI 100 • WTP communication via an AK-PI 100 A maximum of 162 controllers can be connected to a system controller. The system controller cannot handle addresses above 199. The AK-PI 100 has an auxiliary function that can shift a group of addresses, so that you do not need to change the address in each individual MDM and WTP unit. The function is called “address offset”, and informs the AK-SC 255 of the changed addresses. After the function, a unit has the following address: Offset value + configured address of the unit.

Installation Preparing the TCP/IP connection The AK-PI 100 must be linked to the AK-SC 255 physically and also with a software setting. You can do this as follows: 1. Connection Cables are run from the units to a router or to a switch. 2. Setting a) Router - Dynamic: If DHCP is enabled, no settings need to be changed in the router - Static: Check that the static address range does not conflict with the DHCP range b) Switch No direct settings are necessary, but addresses are always static for AK-SC 255 and AK-PI 100 c) AK-SC 255 - Choose static if the AK-SC 255 and AK-PI 100 are connected by a switch or if the system can be accessed from outside. Then configure the IP address (request an IP address from the IT officer of the department). - Select dynamic if the system is self-contained and both units are connected to a router. d) In the AK-PI 100, set IP addressing to either static or dynamic. - Choose static if the AK-SC 255 and AK-PI 100 are linked by a switch. Then configure the IP address (request an IP address from the IT officer of the department). - Select dynamic if the system is self-contained and both units are connected to a router. 3. If a router or switch is connected, turn it on.

AK-PI 100 configuration 1. Set the address on the front to 0 (0 is the factory setting) 2. Switch on 3. Attach the service tool (the service tool can only be used if the address is set to 0) 4. Set AK-PI 100 a. Press the service key button b. Unlock the configuration c. Select System setup d. Enter a name for the controller (the name cannot be seen outside the PI unit yet) e. Select the protocol you want to use (MDM or WTP) f. Select whether you want to use the “Address offset” function g. Switch to IP setup if you are using a static IP address. Configure the address h. Lock the configuration 5. Disconnect the service tool 6. Set the address on the front (for example to 12). The address range is between 11 and 199.

Define the setup of the Woodley units Switch to the displayed screen with: Communications / Refrigeration / Add Controls Specify the description file: • Select No for “Pack controller” • Select the number of controllers (in this example 10) • Click the “Setup” button to switch to the next screen • Click “Edit” on the first controller type (in the “Type” field) • Select the description file matching the controller. Configure the data in the unit: • Go back to the overview screen for all Woodley units • Press “Setup” for the relevant controller type • Set the address. This is the address the unit is set to + any “address offset value” • Edit the name if necessary • Change the settings.

All controller types and software versions will require a description file. Select the relevant file. If the file is not listed, it must be uploaded to the AK-SC 255. Contact Danfoss.

AK-PI 100

Overview of functions in the AK-PI 100 The overview display will show the following: • Status of alarm transmission • Date and time • Quality of the signal for communication with the Woodley MDM unit or to Woodley TPI unit (the value is always 0 if the service tool is attached).

The configuration display gives access to the following: • The configuration lock is used with the following settings: - Communication setting (MDM or WTP) - Address offset setting (addresses are configured for all units on the communication line. If these address values conflict with other addresses, the entire connected group can be “offset”. For example a group of units has the addresses 20 to 31. By setting “Address offset” to 50, the address will become 70 to 81 in the AK-SC 255. This removes the need to change the addresses of the existing units). - Adjustment of a static IP address. • In “System setup” you can give the unit a name • You can change the IP setup
