then poll all slaves via porHCU37003703E , back to port 1, and so on. As each slave is successfully polled, the respective Channel bit is set to 0 in the slave Status register. Remember the LTQ port 1 equals Channel A and the LTQ port 2 equals Channel B. Should a slave not be reached on a poll, the LTQ will set the corresponding Channel Fail bit to 1, switch to the other port and attempt to communicate with the same slave. Should the slave not HCU37003703E communicate from the second port, the corresponding Channel Fail bit will be set to 1, and the LTQ will resume polling on the original port. After the LTQ has completed polling all configured slaves on the first port, the polling routine will switch to the other port and repeat the above process. Example: There are 5 slaves on the network and slave number 3 has been turned off. The LTQ is currently polling the slaves through the LTQ port 1 (Channel A). Slave number 1 and 2 respond to the LTQ port 1 poll. Slave number 3 does not respond to the portHCU37003703E poll causing the LTQ to set slave 3 Channel A bit to 1. The LTQ now changes to port 2 (Channel B) and polls slave number 3. Slave number 3 does not respond to the port 2 poll causing the LTQ to set the slave 3 Channel B bit to 1. Next the LTQ changes back to port 1 and attempts to poll slave number 4. This communication attempt is successful and the LTQ now polls slave number 5 through the LTQ port 1. Slave number 5 responds completing the port 1 poll. Next the LTQ repeats the process through port 2 (Channel B). Slave 1 and 2 respond, slave 3 does not respond and the LTQ sets the slave 3 Channel B bit to 1. The LTQ changes to portHCU37003703E and attempts to communicate with slave 3. Slave 3 does not respond, the LTQ sets the slave 3 Channel A bit to 1, switches back to port 2 and resumes polling the remainder of the configured slaves. Once slaves 4 and 5 have been successfully polled via port 2, the LTQ then switches to port 1 and repeats the polling process.
