Title: SLAVE DEVICE BUSY
Post by: BLUDOTT on October 23, 2016, 09:31:56 PM

hello gang, first of all i wanna say i am loving the advance HMI, im using a idec smart axis 40 I/O plc on modbus tcp, i have it communicating pretty good with all the analog inputs and outputs, i am able to write to the holding regs but when i go to try to write to a simple timer to change the presets value i get (slave device busy), could someone give me some ideas, im trying to change a t001 value and make it hold, my timer value on the plc is T0020 and my modbus address preset value for the timer is 409021 and the modbus adress for the current value is 300021, thanks in advance.

This is an error that comes directly from the device. It is error code 6. Is there a manual on this device that may give a description of Modbus exception code 6?
