About: HostLink Protocol

An Entity of Type: software, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

HostLink is communication protocol for use with or between PLC's made by Omron. It is an ASCII-based protocol generally used for communication over RS232 or RS422. The protocol enables communication between various pieces of equipment in an industrial environment for programming or controlling those pieces of equipment.The maximum allowed message size is 30 words per message. Larger messages can be sent by 'fragmentation' process, where the same slave returns a series of messages to build up the entire response. PLC host computers can transfer procedures, and monitor PLC data area, and control the PLC using the HostLink protocol.

dbo:abstract
  • HostLink is communication protocol for use with or between PLC's made by Omron. It is an ASCII-based protocol generally used for communication over RS232 or RS422. The protocol enables communication between various pieces of equipment in an industrial environment for programming or controlling those pieces of equipment.The maximum allowed message size is 30 words per message. Larger messages can be sent by 'fragmentation' process, where the same slave returns a series of messages to build up the entire response. PLC host computers can transfer procedures, and monitor PLC data area, and control the PLC using the HostLink protocol. (en)
  • HostLink是工業网络传输协议，可以和欧姆龙的PLC通訊，或是兩台PLC之間的通訊。HostLink是ASCII的通訊協定，一般是用RS-232或EIA-422的通訊介面。利用此通訊可以在工業環境下，為工業設備燒錄程式或是進行控制。 一筆訊息的最大長度是30字。較長的訊息會用fragmentation（分片）的技術拆分為數個較小的訊息，同一個從站會送出一連串的訊息，可以以此重組完整的回應訊息。控制PLC的電腦可以用HostLink傳輸程序、監控PLC的資料區，以及控制PLC。 (zh)
