Technical Data for LD 800DN Section 7 Technical Data
214 9ARD000014-600 A
• Total number of Input and Output Bytes along with channel status bytes of the
device configured under one CI873 should not exceed more than 72Kb.
• Configuration assembly (grouping of parameter configuration for an device)
size of 512 bytes is supported per EtherNet/IP/device and 200 bytes is
supported per DeviceNet device.
• Maximum CIP connections supported (including Class 1 and Class 3) per
EtherNet/IP Device is 20.
• The CI873 supports total of 128 connections.
• The CI873 only supports devices which uses EtherNet/IP encapsulation of CIP.
It does not support PCCC, Modbus encapsulation.
• CI873 cannot accept class 1 and class 3 connections from any scanner. That is,
it can act only as master originating CIP connections to EtherNet/IP devices.
• Maximum 1000 bytes per Connection point based Class 1 Connection is
supported where O->T can have maximum of 500 bytes and T->O can have
maximum of 500 bytes.
• Supports only 10 CIP connections with 10ms RPI.
• CI873 does not support FTP commands.
Technical Data for LD 800DN
The technical data that need to be considered while configuring an LD 800DN
linking device (for DeviceNet) are:
• One CI873 supports maximum of 4 LD 800DN.
• The maximum number of input bytes supported by LD 800DN is 496 bytes. If
the total number of input bytes of all the DeviceNet slaves configured under the
linking device exceeds 496 bytes, then the download is stopped.
• The maximum number of output bytes supported by LD 800DN is 492 bytes. If
the total number of output bytes of all the DeviceNet slaves configured under
the linking device exceeds 500 bytes, then the download is stopped.
• Multiple CI873 cannot communicate to same LD 800DN data. That is more
than one CI873 cannot be connected to same LD 800DN at any time.
• The maximum number of DeviceNet connections per device is restricted to 5.
