Thanks Emil for your prompt reply. I'm using the "I" feature, which helps a lot. Precisely, I wanted some sort of "debug" because I CAN send SMS from the PLC (Jazz inits the modem OK), but I CANNOT recieve! I checked the SIM card and it's empty. I connected the Enfora 1308 to the Hyper-terminal in my PC and the Modem do receives SMS. I'm sending exaclty the same words stated on the "sms configuration" menu...but no luck (SB185 and SB186 =0). I guess there is something between the modem and the PLC: the cable?, any special conf under "prepare PLC-side moden" missing?. Any clue? thanks again! Pedro

Hi All, I'm using a Jazz PLC connected to an Enfora 1308 modem using the MJ20-PRG adapter. Is there any way to connect the PLC to my PC in order to debug the ladder program, while keeping Jazz connected to the modem (to see what's going on with the modem!)? Maybe something like a "sniffer" to connect 2 MJ20-CB200 cables -one to the PC and the other to the Modem-? would that work? thanks a lot! regards, Pedro

Hi all, I've been using a Jazz PT15 with 3 PT1000 sensors connected (measuring hot water at a boiler room) very well. I recently installed another PT15 in another room but this time the measurements are very unstable: temp shows correctly (40ºC for example) but jumps every few seconds to 36ºC or 45ºC...a huge gap! I tried the "high" filter, but inputs keep fluctuating a lot. I tested the sensors with another application and they are ok. PLC is grounded. The only issue is that sensors cables run very near other 220V cables May those cables produce noise to the sensors? (I have done that before without any trouble, though). Am I forgetting something / doing something wrong regarding PLC connections? Any help will be highly appreciated!! thanks in advance Pedro
