Abstract
(EN)
An objective of the present invention is to achieve both acceleration in data transfer and uniformity in PLC control periods. Provided is an RFID communication unit comprising: a higher-order communication control part (11) for carrying out communication with a higher-order controller (50) at a prescribed communication period; and an RF communication control part (20) for carrying out reading and/or writing of data with an RF tag (30) through wireless communication. During the communication period in which communication is performed with the higher-order communication control part (11), the RF communication control part (20) concurrently executes the wireless communication with the RF tag (30).
(FR)
Un objectif de la présente invention est d'obtenir aussi bien une accélération du transfert de données que de l'uniformité de périodes de commande PLC. L'invention concerne une unité de communication RFID comprenant : une partie de commande de communication d'ordre supérieur (11) pour effectuer une communication avec un organe de commande d'ordre supérieur (50) lors d'une période de communication prescrite ; et une partie de commande de communication RF (20) pour effectuer une lecture et/ou une écriture de données d'une étiquette RF (30) au moyen d'une communication sans fil. Pendant la période de communication dans laquelle une communication est effectuée avec la partie de commande de communication d'ordre supérieur (11), la partie de commande de communication RF (20) exécute simultanément la communication sans fil avec l'étiquette RF (30).
(JA)
データ転送の高速化と、PLCの制御周期を一定にすることとを両立する。上位のコントローラ(50)との間で所定の通信周期で通信を行う上位通信制御部(11)と、RFタグ(30)との間で無線通信によりデータの読み出しおよび書き込みの少なくともいずれか一方を行うRF通信制御部(20)とを備え、RF通信制御部(20)は、上位通信制御部(11)による通信が行われている通信周期の期間中にRFタグ(30)との無線通信を並行して実行する。
