6.5 How to Read Communications Error Information The result of communications on the E5CK T can be checked by the end code or undefined error response in the response frame. Use this end code or undefined error response to remedy errors that may occur.
F Action Check the communications conditions. If the communications conditions of the host computer and E5CK T controller match, then a probable cause is a problem in the communications circuit of one or both of the host com puter and E5CK T controller.
6.6 Program Example 6.6 Program Example JHow to use programs The program described below obtains corresponding response frame data when some of the command frame data is input. The input format is as follows. The FCS and terminator are automatically generated, and need not be input.
