Supplementary Descriptions of the Special Internal Relays Related to the Communication Functions
■ M8005: Communication Error
When an error occurs during data link communication, M8005 is turned on. The state is retained even when the error is cleared.
■ M8006: Communication Prohibited Flag (When Data Link Master)
During data link communication, communication is stopped while M8006 is on.
■ M8007: Initialization Flag (When Data Link Master)/Stop Communication Flag (When Data Link Slave)
When data link master: When this flag is turned on in the run status, the data link is initialized just once to check the connection
When data link slave : This flag is turned on when communication from the master is interrupted for 10 s or longer. This flag is
■ M8022: User Communication Receive Instruction Cancel Flag (Port 1)
While M8022 is on, user communication (receive instruction) executing on Port 1 is canceled.
■ M8023: User Communication Receive Instruction Cancel Flag (Port 2)
While M8023 is on, user communication (receive instruction) executing on Port 2 is canceled.
■ M8026: User Communication Receive Instruction Cancel Flag (Port 3)
While M8026 is on, user communication (receive instruction) executing on Port 3 is canceled.
■ M8080 to M8117: Data Link Communication Completed Relay
Special internal relays used for data link communication. For details, see "Data Link Communication" on page 7-1.
■ M8184: Change HMI Module Network Settings Trigger
When M8184 is turned on, the values written to D8437 to D8456 are set as the HMI module IP address.
The IP address is not set just by changing the values of D8437 to D8456. For details on changing the HMI module network
settings, see "Network settings by HMI module special data registers" on page 3-5.
■ M8186: Executing Auto Ping
M8186 is on when auto ping is operating. M8186 is off when auto ping is stopped. For details on auto ping, see "Auto Ping
Function" on page 3-18.
■ M8187: Auto Ping Stop Flag
While M8187 is on, auto ping stops. While M8187 is off, auto ping is executed. At that time, auto ping is executed from the
smallest remote host number specified in the remote host list, regardless of the previous end status.
■ M8190: Change CPU Module Network Settings Trigger
When M8190 is turned on, the values written to D8304 to D8323 are set as the CPU module IP address.
The IP address is not set just by changing the values of D8304 to D8323. For details on changing the CPU module network
settings, see "Network settings by special data registers" on page 3-4.
■ M8191: SNTP Acquisition Flag
When M8191 is turned on, the time information is acquired from the SNTP server.
■ M8200 to M8207: User Communication Receive Instruction Cancel Flag
When M8200 to M8207 are turned on, the user communication receive instruction being executed is stopped.
M8200 = User communication receive instruction being executed on client connection 1
M8201 = User communication receive instruction being executed on client connection 2
M8202 = User communication receive instruction being executed on client connection 3
M8203 = User communication receive instruction being executed on client connection 4
M8204 = User communication receive instruction being executed on client connection 5
M8205 = User communication receive instruction being executed on client connection 6
M8206 = User communication receive instruction being executed on client connection 7
M8207 = User communication receive instruction being executed on client connection 8
