It could affect the transmitting signals from the instruments (Noise) and there will be a losses in this signal unless you installed the control cables on separated trays and not mix it with power cable. In addition you've to be assure that the shield wire at control cable grounded from one side, either from  the field instrument or from controller in the control unit to improve the signal.
