Warning: The ICX35-HWC should not receive SMS messages faster than once every 30 seconds;
otherwise it may repeatedly disconnect from the cellular network.
Warning: The ICX35-HWC must not buffer more than 500 received SMS messages before
transmission to RSLogix 5000; otherwise, new incoming messages will be discarded.
Check the number of free slots in the Rx buffer by continuously monitoring the
SMS_MSGs_Rx_Free_Buffer_Counter tag (Starting value is 500). The ICX35-HWC may buffer
SMS messages in case the messages are received from the cellular network faster than the PLC
polling rate. If a receiving PLC is offline during the sending of more than 250 SMS messages, upon
reconnection, it will only poll the last 250 received SMS messages.
For reliable communications, the number of free slots in the ICX35-HWC receive buffer should be
greater than '0'. Otherwise, messages received when the buffer is full are discarded.
