For example in online manual, there is 5 modes, andGET_DIAG have "CHANNEL" parameter, but in "s7 1200 prog. controller" only 3modes and noCHANNEL.... Any way, i need to get status from the channels of "sm 1221", "sm 1222", but, as i read in mauals, they have not such deagnostic, is it? it's alsoreferto sm 321 and 322.

So, if i have s7 - 1214 with i/o modules, profibusconnectedto IM 153-2 with i/o modules, then i have to use "DeviceStates" function to control modul's (DI/DO) status . Am i?

Am i? Hello ROLLEX, For just the basic IO communication (as in your case for DI / DO) in PROFIBUS with S7-1200 you do not need additional programming blocks. DeviceStates is used to determine the I/O device operational states of an I/O subsystem. The status type can assume the following. 1: Configuration of device is active or not yet complete. 2: Device defective 3: Device disabled 4: Device exists

ROLLEX

p.s. what is the function of i/o system, i/o device. i/o sub.....and so on?

Hello ROLLEX,

FYI

Number	PROFINET	PROFIBUS	Note
①	PROFINET IO system	DP master system
②	IO controller	DP master	Device used to address the connected IO devices/DP slaves. This means that the IO controller/DP master exchanges input and output signals with field devices. The IO controller / DP master is often the controller on which the automation program runs.
③	Programming device / PC (PROFINET IO supervisor)	Programming device/PC Class 2 DP master	Programming device / PC / HMI device used for commissioning and diagnostics
④	PROFINET / Industrial Ethernet	PROFIBUS	Network infrastructure
⑤	HMI (Human Machine Interface)	HMI	Device for operating and monitoring functions.
⑥	IO device	DP slave	Distributed field device assigned to one of the IO controllers / DP masters, for example, distributed IO, valve terminal, frequency converter, and switches with integrated PROFINET IO functionality.
⑦	I-device	I slave	Intelligent IO device and intelligent DP-slave.

I know about OB82, but "multierror" is not fully do for me. Hello ROLLEX, 1. What do you mean by detect DI / DO PROFIBUS and local error status?? 2. OB 82 works with the diagnostics-capable modules. and again what exactly do you mean by multierror (does this mean multiple error happening at same instance of time)?

OB 82 works with the diagnostics-capable modules. and again what exactly do you mean by multierror (does this mean multiple error happening at same instance of time)? In the interface of OB82, one of the inputs is a bool named multierror. It means multiple errors exist meaning a smart loop must be done inside OB82 to figure out all the error reasons. I have tried figuring it out, but the documentation was lacking to figure out what to do with the multierror bit.
