3100-mcm configuration, any exprience users here? pls help !

Hi,

I'm having problem configuring a 3100-MCM(master) with 4 ROC(slave) devices in site. I managed to write data to each of the ROC device one at a time, but when i write data to 4 ROC at the same time, the error LED on the 3100-mcm 'ON' while the tx & rx is blinking.

ROC SLAVE ADDRESS = 1, 2, 3 & 4

My second problem is the compare word n107:310 (for BTW) will cycle from 7, 8, 9, 10, 80, & 81, how can i configure the compare word N107:310 in order to cycle to become 4, 5, 6, 7, 8,.....

The sample files downloaded MCM5EX1M.RSP downloaded only shows one slave device, how can i configure for 2 slave devices? Let's say each of them mapping 40 words?

word N107:50 is activated to write data to the slave ROC 1, when N107:60 is also activated to write date to the slave ROC 2, err LED on the 3100-MCM on and tx & rx blinks.
