5.9 ABLOGIX IO Server 5.9.1 Introduction General Reference Guide IO Servers Configuration ABLogix IO server is used to communicate with Allen Bradley Logix Series PLCs on the Ethernet link or on the Serial link (in DF1 protocol). • It allows the eWON to poll ABLOGIX PLCs in order to read data. • It allows the eWON to act as EIP-DF1 gateway for remote maintenance of the ABLOGIX PLCs. • It allows the eWON to poll DH+ device using ControlLogix gateway. The eWON only allows DF1 communication with devices directly connected to the eWON Serial link (the ABLOGIX PLC may not be located behind another PLC connected on the DF1 serial link acting itself as gateway). note: Please check in the “Rockwell compatibility matrix” on page 221 if your device is supported. 5.9.2 Setup Figure 97: ABLOGIX IO server setup window RG-001-0-EN ver 1.14 eWON® - 02/05/2012 - ©eWON sa Page 123
5.9.2.1 Communication Setup General Reference Guide IO Servers Configuration In the current implementation, the serial link configuration may be done using the DF1 IO Server configuration page or the AB LOGIX IO server page. The same settings apply for both IO servers (DF1 and ABLogix). note: In the config.txt file the serial link parameters are defined in the DF1 IO server entry. Baud Rate Select the Baudrate from 1200 to 38400 Bauds Parity The parity to apply: none / odd / even Stop Bit(s) Number of stop bits Frame Error Detection Cyclic Redundancy Check (CRC) or Block Check Character (BCC) HW mode Full Duplex no handshaking or Half duplex Master Response Timeout 5.9.2.2 Topic configuration Three topics can be used for the IO Server. These topics are used to give a common property, to a group of Tags, like: • Enable/Disable • Global Device Address • Poll rate 5.9.2.2.1 ABLogix : DF1 serial link The Global Device Address has the following syntax: Address • Address = DF1 Node ID of the device (i.e.: 5) Maximum time the eWON will wait for a valid message from the DF1 master. This value can be critical for a correct operation, depending on the responsiveness of the master. A value of 1000 should be selected to guarantee correct operation Rx message timeout (MSEC) Maximum time between a request is posted and the response is received Tx message timeout (MSEC) Maximum time for a request to be sent eWON DF1 address Device Address of eWON on DF1 link When the eWON acts as a DF1 slave, it will respond to 2 consecutive link addresses; doing this improves the throughput of data across the eWON when acting as a gateway. (eWON DF1 address and eWON DF1 address +1) Destination DF1 address Device Address of Destination on DF1 link when EIP is used Bridge EIP connection When bridging is configured, EIP connections requests are forwarded to the PLC on the DF1 interface (mandatory for Logix family). This is the default configuration. When not configured, connection requests are cancelled by the eWON (must be disabled for SLC family). Table 98: ABLOGIX-DF1 communication setup controls Topic configuration item Description Topic enabled Enables or disables the polling of all the Tags in the topic Global Device Address Poll rate The Global Device Address is a global parameter for all the Tags of the topic. See below for the Device Address syntax. If an address is specified here, it will replace (overload) the address defined Tag by Tag Defines the refresh rate (in mSec) of the Tag name. In a complex application, we can imagine that some Tag name must be refreshed every second – typically for digital input - and other every minute – typically: temperature- Table 99: ABLOGIX topics configuration setup Figure 98: ABLogix : DF1 address example RG-001-0-EN ver 1.14 eWON® - 02/05/2012 - ©eWON sa Page 124
